llrint(3M)		Mathematical Library Functions		    llrint(3M)

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  feclearex‐
       cept(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 argu‐
       ment, they raise the inexact floating-point exception.
