LRINT(3)                NetBSD Library Functions Manual               LRINT(3)


NAME

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


LIBRARY

     Math Library (libm, -lm)


SYNOPSIS

     #include <math.h>

     long long
     llrint(double x);

     long long
     llrintf(float x);

     long
     lrint(double x);

     long
     lrintf(float x);


DESCRIPTION

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

     The llrint(), llrintf(), and lrintf() functions differ from lrint() only
     in their input and output types.


RETURN VALUES

     The llrint, llrintf, lrint, and lrintf functions return the integer near-
     est 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.


SEE ALSO

     math(3), rint(3), round(3)


STANDARDS

     The llrint(), llrintf(), lrint(), and lrintf() functions conform to
     ISO/IEC 9899:1999 (``ISO C99'').
