+ Addition symbol. Returns the sum of two numbers, the term-by-
term sum of two lists or two matrices, or adds two strings
together.
− Subtraction symbol. Returns the difference of two numbers, or
the term-by-term subtraction of two lists or two matrices.
.* List or matrix multiplication symbol. Returns the term-by-term
multiplication of two lists or two matrices.
List1.*List2
or Matrix1.*Matrix2
Example:
[[1,2],[3,4]].*[[3,4],[5,6]] gives
[[3,8],[15,24]]
./ List or matrix division symbol. Returns the term-by-term division
of two lists or two matrices.
.^ Returns the list or matrix where each term is the corresponding
term of the list or matrix given as argument, raised to the
power n.
List.^Integer
or Matrix.^Integer
/ Division symbol. Returns the quotient of two numbers, or the
term by term quotient of two lists. For division of a matrix by
a square matrix, returns the left-multiplication by the inverse of
the square matrix.
:= Stores the evaluated expression in the variable. Note that:=
cannot be used with the graphics variables G0–G9. See the
command BLIT.
var:=expression
Example:
A:=3 stores the value 3 in the variable A
< Strict less-than-inequality test. Returns 1 if the left side of the
inequality is less than the right side, and 0 otherwise. Note
that more than two objects can be compared. Thus 6 < 8 <
11 returns 1 (because it is true) whereas 6 < 8 < 3 returns 0
(as it is false).
<= Less than or equal inequality test. Returns 1 if the left side of
the inequality is less than the right side or if the two sides are
equal, and 0 otherwise. Note that more than two objects can
be compared. See comment above regarding <.
