mod() MATH/Number menu
mod(

) ⇒
expression
mod(
list1
,
list2
) ⇒
list
mod(
matrix1
,
matrix2
) ⇒
matrix
Returns the first argument modulo the second
argument as defined by the identities:
mod(x,0) r x
mod(x,y) r xì y floor(x/y)
When the second argument is non-zero, the result is
periodic in that argument. The result is either zero or
has the same sign as the second argument.
If the arguments are two lists or two matrices,
returns a list or matrix containing the modulo of
each pair of corresponding elements.
