llrintl
ANSI_SYNOPSIS
#include <math.h>
long long int llrint(double x);
long long int llrintf(float x);
long long int llrintl(long double x);
TRAD_SYNOPSIS
ANSI-only.
DESCRIPTION
The <<llrint>>, <<llrintf>> and <<llrintl>> functions round <[x]> to the nearest integer value,
according to the current rounding direction. If the rounded value is outside the
range of the return type, the numeric result is unspecified. A range error may
occur if the magnitude of <[x]> is too large.
RETURNS
These functions return the rounded integer value of <[x]>.
<<llrint>>, <<llrintf>> and <<llrintl>> return the result as a long long integer.
PORTABILITY
<<llrint>>, <<llrintf>> and <<llrintl>> are ANSI.
<<llrint>>, <<llrintf>> and <<llrintl>> are only available on i386 platforms when
hardware floating point support is available and when compiling with GCC.
