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.
