NAME
llround() - round to long long function
SYNOPSIS
#include <math.h>
long long llround(double x);
DESCRIPTION
llround() rounds its argument to the nearest integral value. An argument exactly halfway between
two integers is rounded away from zero, regardless of the current rounding direction. Rounding away from
zero also applies to the functions, roundand lround.
If the rounded value is outside the range of long long, the numeric result is unspecified.
The ISO/ANSI C committee has approved the llround() function for inclusion in the C9X draft stan-
dard.
To use this function, compile either with the default -Ae option or with the -Aa and -D_HPUX_SOURCE
options. Make sure your program includes <math.h
>. Link in the math library by specifying -lm on the
compiler or linker command line.
RETURN VALUE
The
llround() function returns the rounded long long value.
ERRORS
No errors are defined.
