NAME
       llrint, llrintf, llrintl - round to nearest integer value using current rounding direction

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <math.h>

       long long llrint(double x);

       long long llrintf(float x);

       long long llrintl(long double x);

DESCRIPTION
       These functions round their argument to the nearest integer value, rounding according to the current rounding direction.

RETURN VALUES
	Upon successful completion, these functions return the rounded integer value.

       If x is NaN, a domain error occurs and an unspecified value is returned.

       If x is +Inf, a domain error occurs and an unspecified value is returned.

       If x is -Inf, a domain error occurs and an unspecified value is returned.

       If the correct value is positive and too large to represent as a long long, a domain error occurs and an unspecified value is returned.

	If the correct value is negative and too large to represent as a long long, a domain error occurs and an unspecified value is returned.

ERRORS
       These functions will fail if:

       Domain Error    The x argument is NaN or +-Inf, or the correct value is not representable as an integer.

		       If  the	integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, then the invalid floating-point exception will
		       be raised.

USAGE
       An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before  calling	these  functions.  On  return,	if
       fetestexcept(FE_INVALID	|  FE_DIVBYZERO  |  FE_OVERFLOW  |  FE_UNDERFLOW) is non-zero, an exception has been raised. An application should
       either examine the return value or check the floating point exception flags to detect exceptions.

       These functions provide floating-to-integer conversions. They round according to the current rounding direction. If the	rounded  value	is
       outside the range of the return type, the numeric result is unspecified and the invalid floating-point exception is raised. When they raise
       no other floating-point exception and the result differs from the argument, they raise the inexact floating-point exception.
