Introduction to Using CoCalc

CoCalc is a Reverse-Polish-Notation (RPN) scientific calculator.RPN calculatorswere popularized by Hewlett-Packard's great calculators. (If you buy areal calculator, get one from HP: they are well-designed, well-built, andreasonably priced. You can even visit the un-official HP calculatormuseum.)

On ordinary, non-RPNcalculators, you do calculations by pressing buttons in the order thatyou would write an equation on paper (e.g., 5 - 2 = ).On RPN calculators,you enter the numbers and and then do something to them(e.g., 5 Enter2 - ). You will note that RPN calculators don't have an= button orparentheses buttons, but they do have an Enter button.

If you aren't used to it, RPN seems odd at first. But when youget used to it and use it for non-trivial calculations, you will seethat it is a wonderful system.

Return to the calculator.

Entering Numbers

For simple numbers, just press the appropriate buttons. For example,to enter 45.68, press: 4 5 . 6 8.

To enter a number with an exponent: after entering the mantissa of thenumber, press eex, and then enter the exponent. For example,to enter 4.56*10^5, press 4 . 5 6 eex 5. The display willshow 4.56e5, which is the program's notation the numbers withexponents.

To make a number negative, type the number and then press chs(change sign). For example, to enter -4.56, press 4 . 5 6 chs.You can press chs repeatedly to add/remove the minus sign.

To make an exponent negative, press chs (change sign) afteryou have entered the exponent. For example,to enter 4.56*10^-5, press 4 . 5 6 eex 5 chs. The display willshow 4.56e-5, which is the program's notation the numbers withexponents.

For many of the buttons, you can also type the similarly named keys.This works for the following keys: 0 1 2 3 4 5 6 7 8 9 a A b B c C d D e E f F ^ ! % . / x - + Enter backspace.The buttons that they correspond to should be obvious.Also supported are ',' (an alias for '.') and'*' (an alias for 'x').Warning: note that '-' corresponds to the subtraction button ('-');to change the sign of a number, you must use the 'chs' button.

Return to the calculator.

The Stack

The stack consists of 4 registers (slots which hold numbers), which arenamed: x, y, z, and t.When you enter a number, it is constructed in the x register.

When youhave finished entering a number, you can do something to the number(e.g., press a button that does something to the value in the x register,like 10^x), or you can enter another number (press Enterand then start entering the next number.

Many buttons are commands that use the values in the x and y registers,e.g., +. When you use these, the result is placed in x, and thevaluesin the z and t registers are move down: y= previous z, z= previous t.The t register is not changed.

There are 3 important keys for manipulating the numbers in the stack:

• Enter - this button pushes all of the values upwards.The x valuestays in x and is also pushed into y; y goes into z; z goes into t;and t goes into oblivion.For example, press 1 Enter 2 Enter Enter.
• rollDn - this rolls down all of the registers.The t value movesto z; z moves to y; y moves to x; x moves to t.For example, press 3 Enter 4 rollDn rollDn rollDn rollDn.
• x<->y - this button swaps the values in the x and yregisters. For example, press 5 Enter 6 x<->y.

Automatic stack lift: After you use a command (e.g., ln or+), you can immediately enter another number; you don't needto press Enter to lift all of the values in the stack.After a command, if you press a digit, CoCalcwill automatically lift the stack (as if you had pressed Enter).

Return to the calculator.

Operations

The basic approach to using CoCalc is: enter numbers into the registers(for example, press 2 Enter 3) and do things to them(press +).This is clearly not the same as entering an equation, but with a littlepractice it will become easier. Sometimes, you will see that there aretwo general approaches: 1) enter the numbers in the order they occurin the equation, using operators when the proper values are in theproper registers, and 2) start with the part of the equation that iswithin parentheses. These techniques are illustrated below.

Here are some simple equations and the buttons you need to press todo the calculation in CoCalc:

Problem: square root(9)=
Solution: press 9 x^0.5

Problem: 8/5=
Solution: press 8 Enter 5 /

Problem: 4 + (5*6) =
Solution 1) Press: 4 Enter 5 Enter 6 * +.
Solution 2) Press: 5 Enter 6 * 4 +. Note that you don't have topress Enter before typing 4; the stack is automaticallylifted when you start typing a number after doing an operation.

Problem: 3*sin(1.5degrees)=
Solution 0) For either method, press Deg so the calculations will bedone in degree mode.
Solution 1) Press: 3 Enter 1.5 sin *.
Solution 2) Press: 1.5 sin 3 *.

Problem: (16/5.6 + .5) / (pi*.8^2 + 4)
Solution: press 16 Enter 5.6 / .5 + pi Enter .8 x^2 * 4 + /

For more complicated equations or if you repeatedly use a constant,you may want to store values in a storage register.
Problem: Convert several length measurements (in inches) into centimeters.
Solution: Press 2.54 Store 0,then repeatedly press (a number) Recall 0 *

Return to the calculator.

Degrees vs. Radians

There are two units commonly used to measure angles: degrees and radians.A completecircle spans 360 degrees. A complete circle spans 2*pi radians. Sometimesit is easier to work in degrees; sometimes in radians. CoCalc canwork with either.

Show me book pdf. The Deg and Radradio buttons let you choose which mode will be used for subsequenttrigonometric operations (sin, cos, tan, asin, acos, atan,->Rec, ->Pol).

The ->Deg and ->Radbuttons let you convert an angle value in the x register fromradians to degrees, or from degrees to radians, respectively.

Return to the calculator.

Display Options

Numbers can be displayed in different ways. The Fix, Sci,and Eng optionsall display numbers in base 10, but with slightly different ways ofdetermining how many digits will be shown and how the exponentwill be shown. The Hex and Bin options displayrounded values in base16 and base 2 respectively.

For all of these options, the numbersstored in the registers are not changed; the numbersare just displayed in different ways.

Fix - This format always shows a fixed number of digitsto the right of the decimal place.To select the Fix display mode and specify the number ofdigits to the right of the decimal point,press Fix and then the desired number of digits, 0 - F.For example, 98765.12345 appears as 98765.123if you use Fix 3.The last digit is rounded.If the number is too big or too small, scientific notation will be used.

Sci - Scientific notation always displays the numberwith one digit to the left of the decimal place, some specifiednumber of digits to the right, and an exponent.To select the Sci display mode and specify the number of digitsto the right of the decimal point,press Sci and then the desired number of digits, 0 - F.For example, 98765.12345 appears as 9.877e+004if you use Sci 3.The last digit is rounded.

Eng - Engineering notation is similar to scientificnotation, except that the exponent is constrained to be a multipleof 3.To select the Eng display mode and specify the number ofdigits to the right of the decimal point,press Eng and then the desired number of digits, 0 - F.For example, 98765.12345 appears as 98.765e+003if you use Sci 3.The last digit is rounded.[HP calculator purists: no, this is not exactly the way HP does it. Butthis way makes the decimal points line up nicely.]

Hex - The Hex option displays the numbers in the registersby displaying rounded values in base 16.Hexadecimal, as base 16 is called, is widelyused by computer programmers. When you are typing in numbers in this mode,you can use digits 0 - 9 andadditional hex digits (A, B, C, D, E, and F) which stand for the base10 numbers: 10, 11,12, 13, 14, and 15, respectively. Because the calculator only workswith integer hexadecimal numbers,you can't use the . or eex keys in Hex mode. Negative numbersare displayed with a '-' sign, which avoids a problem: thereare two common ways to store negative numbers in Hex notation(two's complement and one's complement) and the number of digits is differentfor 16, 32, and 64 bit numbers.To select the Hex display mode, press Hex.

Bin - The Bin option displays the numbers in the registersby displaying rounded values in base 2.Binary, as base 2 is called, is widelyused by computer programmers. When you are typing in numbers in this mode,you can only use digits 0 and 1. Because the calculator only workswith integer binary numbers,you can't use the . or eex keys in Bin mode.Negative numbersare displayed with a '-' sign, which avoids a problem: thereare two common ways to store negative numbers in Bin notation(two's complement and one's complement) and the number of digits is differentfor 16, 32, and 64 bit numbers.Since binary notation is not very dense, you will get an error messageif a number is too long to display.To select the Bin display mode, press Bin.

Storage Registers

There are 16 registers (slots) into which you can store, and later retrieve,numbers.

To store the current x value, press store and thenumber of the register into which you want to store it (0 - F),e.g., store 4.

To recall a stored number and put it in x (as if you typed it in), pressrecall and the number of the register from which you are gettingit (0 - F), e.g., recall 4.

You can set all of the storage registers to 0 by pressing clrReg.

Registers 0 - 5 are used by the statistics procedures to holdvarious sums. So, before using the statistics procedures,use clrReg. Until you are done with statistics don't storeanything in registers 0 - 5.

Return to the calculator.

Statistics

CoCalc can do calculate simple correlation and linear regression statistics.To do so:

1. Initialize the statistics system by pressing clrReg.Storage registers 0 - 5 are used by the statistics procedures to holdvarious sums. So, while using the statistics procedures, don't storeanything new in registers 0 - 5.
2. For each x,y pair of numbers, type the y value, press Enter,type the x value, and press Sig+. When you press Sig+, theprogram increments the storage registers(s0=s0+1, s1=s1+x, s2=s2+x^2, s3=s3+y,s4=s4+y^2, s5=s5+xy,) and displays the s0 value in x.These values will be used to calculate various statistics.
3. When you are done entering the data, press any of the statistics keys:
   • mean - Sets x=the mean of the x values, y=the mean of the y values, z=z, t=t.
   • S.D. - Sets x=the standard deviation of the x values, y=the standard deviation of the y values, z=z t=t.
   • L.R. - Linear Regression: x=intercept, y=slope, z=z, t=t.
   • x^,r - Given a y value in the x register, this sets x=expected x, y=correlation coefficient (r), z=z, t=t.
   • y^,r - Given an x value in the x register, this sets x=expected y, y=correlation coefficient (r), z=z, t=t.

If you make a mistake or wish to remove an x,y pair from the statistics,you can enter the x,y values and press Sig-.

All of the discussion above presumes you have x,y pairs. However,most of the statistics procedures (Sig+, Sig-, mean, S.D.)can be used if you just have x values.

Return to the calculator.

Precision and Errors

• Precision: All registers (x,y,z,t and storage) are 64 bit doubles that have roughly 17-18 significant decimal digits and a range of +/-1e300. The +/-1e300 limit is slightly smaller than the true range of doubles; CoCalc restricts it to help avoid numeric errors.
• Integer precision: Calculations that are done on rounded values (e.g., div, mod, <<, >>, and, or, xor, not) are done on 64 bit integers (called 'long's'). Unfortunately, since the precision of doubles is slightly less than the precision of long's, the full range of long's is not available. This should only be a problem in truly extreme cases (e.g., numbers greater than 1e17).
• Errors: CoCalc tries to catch and prevent numeric overflows, division by 0, sqrt, log or ln of a negative number, and other errors. Any calculation that leads to a value greater than +/-1e300 (and some that lead to +/-1e295) lead to an error message. Any calculation done with a error value leads to an error (e.g., 1+error=error).
• Clearing Errors: You can clear an error value in the x register by pressing clx
• Round-off errors: Computers are not good at exactly storingdecimal values. After a series of calculations this often leads to thesituation where the internal value of a number is not exactly whatyou expect (e.g., what appears as 100.0000 may be99.9999999999 internally).Usually, this doesn't matter, because the numbers are roundedwhen they are displayed (e.g., Fix 4 will show you 100.0000).But if you subsequently use int the result will be 99 andthe result of frac will appear as 1(although it is 0.9999999999 internally)!There isn't much you can do about this; just be aware of it.

Set x=sin(x), y=y, z=z, t=t. This assumes that the original x value is an angle in Radians or Degrees, depending on the current Rad or Deg setting. See Degrees vs. Radians.

store

Store x in a slot (0 - F). For example, to store the x value in slot 5, press store 5. See Storage Registers.

tan

Set x=tan(x), y=y, z=z, t=t. This assumes that the original x value is an angle in Radians or Degrees, depending on the current Rad or Deg setting. See Degrees vs. Radians.

x^0.5

Set x=square root of x, y=y, z=z, t=t.

x<->y

Swap the x and y register values, z=z, t=t. See The Stack.

x^2

Set x=x^2, y=y, z=z, t=t.

x^,r

Given a y value in the x register, this sets x=expected x, y=correlation coefficient (r), z=z, t=t. See Statistics.

xor

Set x=round(y) xor round(x), y=z, z=t, t=t.xor compares the two numbers bit by bit. If one bit is 0 and the other is 1, the resulting number has a 1 for that bit.

y^x

Set x=y^x, y=z, z=t, t=t.

y^,r

Given a x value in the x register, this sets x=expected y, y=correlation coefficient (r), z=z, t=t. See Statistics.
