SYNOPSIS

   #include <math.h>

   long long llrint(double x);
   long long llrintf(float x);
   long long llrintl(long double x);

DESCRIPTION

llrint converts its argument to an integral value using the current rounding mode and returns it as a long long integer.

The function name llrintf should be used for float arguments, and llrintl for long double arguments. Alternately, if the header file tgmath.h is included, llrint may be used with any numeric argument type.

RETURN VALUE

llrint returns its argument converted to a long long integer. If the result is outside the range of long long integer, the return value is unpredictable.

IMPLEMENTATION

llrint is implemented as a built-in function unless it is undefined by a #undef statement.
