NAME
     trunc, truncf, truncl - round to truncated integer value

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include

     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 trun-
     cated integer value.


     If x is NaN, a NaN is returned.
