NAME
|
|
int - return the integer part of a number or of numbers in a value
|
|
|
|
SYNOPSIS
|
|
int(x)
|
|
|
|
TYPES
|
|
If x is an object of type xx, int(x) requires xx_int to have been
|
|
defined; other conditions on x and the value returned depend on
|
|
the definition of xx_int.
|
|
|
|
For other x:
|
|
|
|
x number (real or complex), matrix
|
|
|
|
return number or matrix
|
|
|
|
DESCRIPTION
|
|
If x is an integer, int(x) returns x. For other real values of x,
|
|
int(x) returns the value of i for which x = i + f, where i is an
|
|
integer, sgn(f) = sgn(x) and abs(f) < 1.
|
|
|
|
If x is complex, int(x) returns int(re(x)) + int(im(x))*1i.
|
|
|
|
If x is a matrix, int(x) returns the matrix m with the same structure
|
|
as x in which m[[i]] = int(x[[i]]).
|
|
|
|
EXAMPLE
|
|
; print int(3), int(22/7), int(27/7), int(-3.125), int(2.15 - 3.25i)
|
