abs() The abs() command returns the absolute value of an expression. The absolute value of a real number is the number of units from 0 the number is. The absolute value of 9 for example is 9 because it is that many units away from zero. The absolute value of -9 however is 9. abs() will always return a positive value. Examples: :abs(7) returns 7 :abs(-7) returns 7 :1→i :abs(3+4i) returns 7
and The and operator combines two conditions into one, which will be true if both sides are true, and false otherwise. You can create these conditions with the relational operators =, ≠, >, ≥, <, and ≤, with functions such as isPrime(), pxlTest(), and ptTest(), or with any other expression that returns 'true' or 'false'. Other operators for dealing with conditions are or, xor, and not. :2+2=4 and 1=0 false :2+2=4 and 1+1=2 true The operator can also be applied to integers, treating them as 32-bit signed integers (larger integers will be truncated to fit) expressed in binary. The bits will be matched up, and "and" will be applied to the bits individually — a bit in the result will be 1 if the two corresponding bits of the original integers were 1, and 0 otherwise. X or Y and Z will be interpreted as: X or (Y and Z)
AndPic The AndPic command logically takes the picture variable specified, and takes the current graph, and it finds the points at which both the graph and the picture have pixels, and it displays them only. If specified, [row,column] tells where the top left corner of the picture is to be placed. If not specified, the default is (0,0), which is the top left corner of the screen.
angle() Command returns the angle of a complex number.
ans() The Ans(x) holds the last answers that were stored. if x=1 then first answer, x=2 then second, ect.
approx() The approx() command forces an expression to be evaluated in approximate mode, temporarily ignoring the mode setting. Example: :approx(π) returns 3.14159265359
arcLen()
augment() when lists are used as arguments, a list is returned that is list2 appended to list1 Example: :augment({1,⁻3,2},{5,4})
avgRC()

ceiling()
cFactor()
char() The char() command converts an integer between 0 and 255 to the corresponding ASCII character.
Circle The Circle command allows a person to draw a circle on the graphscreen. It can be drawn using the given keystrokes, or it can be called at the homecreen by typing it out. Example: Circle 0,0,5 Will draw a circle with a center of (0,0) and a radius of five.
ClrDraw The ClrDraw command is useful clearing away something drawn on the graph screen
ClrErr
ClrGraph
ClrHome Resets the cursor position to the top left corner of the home screen.
ClrIO This is used to clear the IO buffer (not the home screen). The IO buffer is where any Output(), Disp, Pause, and any other commands that use the I/O buffer display results. Example: :hellowld() :Prgm :ClrIO :Disp "HELLO, WORLD!" :Pause :ClrIO :DispHome :EndPrgm

InputStr The InputStr command allows you to input a string to a variable. Since Input doesn't support the storing of strings into variables, you have to use this command to do that. Keep in mind that the inputted variable cannot be the name of a preexisting variable or flash application that is locked, protected, or archived. For example, if you had a program named "a" or "hello", the command wouldn't work because it is already in use. Examples: :InputStr A :InputStr hello
