trunc(3M) Mathematical Library Functions trunc(3M) NAME
trunc, truncf, truncl - round to truncated integer value SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <math.h> double trunc(double x); float truncf(float x); long double truncl(long double x); DESCRIPTION
These functions round their argument to the integer value, in floating format, nearest to but no larger in magnitude than the argument. RETURN VALUES
Upon successful completion, these functions return the truncated integer value. If x is NaN, a NaN is returned. If x is +-0 or +-Inf, x is returned. ERRORS
No errors are defined. ATTRIBUTES
