NAME
trunc - truncate a value to a number of decimal places
SYNOPSIS
trunc(x [,j])
TYPES
x real
j int
return real
DESCRIPTION
Truncate x to j decimal places. If j is omitted, 0 places is assumed.
Specifying zero places makes the result identical to int().
Truncation of a non-integer produces values nearer to zero.
EXAMPLE
; print trunc(pi()), trunc(pi(), 5)
3 3.14159
; print trunc(3.333), trunc(3.789), trunc(3.333, 2), trunc(3.789, 2)
3 3 3.33 3.78
; print trunc(-3.333), trunc(-3.789), trunc(-3.333, 2), trunc(-3.789, 2)
-3 -3 -3.33 -3.78
LIMITS
0 <= j < 2^31
LINK LIBRARY
