NAME
     trunc, truncf - nearest integral value with magnitude less than or equal
     to |x|

SYNOPSIS
     #include 

     double
     trunc(double x);

     float
     truncf(float x);

DESCRIPTION
     The trunc() and truncf() functions return the nearest integral value with
     magnitude less than or equal to |x|.  They are equivalent to rint() and
     rintf() respectively, in the FE_TOWARDZERO rounding mode.

SEE ALSO
     ceil(3), floor(3), math(3), nextafter(3), rint(3), round(3)
