Quick reference guide
to functions and commands
The function or command name is shown in
bold text as the first line of the description. The
lines immediately following show the arguments,
if any. Arguments are shown in italic text.
Optional arguments are shown in square
brackets []. expr is an expression, var is a
variable. If a function can accept more than one
type of argument, they may be shown on one
line separated by commas, for example,
(expr), (list), (matrix)
If a function may optionally take no arguments,
that is indicated as (). Program and function
structures may be shown with statements
separated with the colon :, which is the symbol
actually used for that purpose in programs.
Functions and commands indicated with
symbols are shown at the end of the reference
guide.
abs()
(expr), (list), (matrix)
Return absolute value of real argument or
modulus of complex argument.
and
expr1 and expr2
list1 and list2
matrix 1 and matrix 2
Return true or false or a simplifed form.
integer1 and integer2
Bit-by-bit 32-bit integer compare. Arguments
larger than 32-bit signed values are reduced
with symmetric modulo operation. Mode must
be Auto or Exact.
AndPic picVar [, row, column]
Logical-AND of graph screen and picvar at (row,
column); default is (0,0)
angle()
(expr), (list), (matrix)
Return angle of arguments interpreted as
complex numbers. Undefined variables are
treated as real variables.
ans()
(), (integer)
Return answer from home screen. integer can
be 1 to 99; not an expression; default is zero.
approx()
(expr), (list), (matrix)
Evaluate argument as decimal value if possible.
Archive var1[,var2] [,var3] ...
Move variables to flash ROM.
arcLen()
(expr,var,start,end), (list,var,start,end)
Return arc length of expression (or each
element of list) with respect to var from start to
end.
augment()
(list1,list2)
Return list which is list2 appended to list1
(matrix1,matrix2)
Append matrix2 appended to matrix1 as
columns.
(matrix1;matrix2)
Append matrix2 to matrix1 as rows.
avgRC(expr,var [,h])
Return forward-difference quotient (average rate
of change) of expr with respect to var. h is the
step value; if omitted, h=0.001
▶
▶▶
▶Bin
integer1▶Bin
Convert integer1 to binary. Non-decimal
integers must be preceeded with 0b or 0h.
Arguments larger than 32-bit signed values are
reduced with symmetric modulo operation.
BldData [datavar]
Create the data variable datavar based on the
current graph settings. If datavar is omitted, the
system variable sysdata is used. The variable is
a table of function values evaluated at each plot
point.
ceiling()
(expr), (list), (matrix)
Return the nearest integer that is greater than or
equal to expr or each element of list or matrix.
Argument may be real or complex.
cFactor()
(expr[,var])
