NAME

     llrint, llrintf, llrintl, lrint, lrintf, lrintl -- convert to integer


LIBRARY

     Math Library (libm, -lm)


SYNOPSIS

     #include <math.h>

     long long
     llrint(double x);

     long long
     llrintf(float x);

     long long
     llrintl(long double x);

     long
     lrint(double x);

     long
     lrintf(float x);

     long
     lrintl(long double x);


DESCRIPTION

     The lrint() function returns the integer nearest to its argument x
     according to the current rounding mode.

     The llrint(), llrintf(), llrintl(), lrintf(), and lrintl() functions dif-
     fer from lrint() only in their input and output types.


RETURN VALUES

     The llrint, llrintf, llrintl, lrint, lrintf, and lrintl functions return
     the integer nearest to their argument x according to the current rounding
     mode.  If the rounded result is too large to be represented as a long
     long or long value, respectively, the return value is undefined.

STANDARDS

     The llrint(), llrintf(), llrintl(), lrint(), lrintf(), and lrintl() func-
     tions conform to ISO/IEC 9899:1999 (``ISO C99'').
