may be available only with certain extended compilers.
Compute the whole number nearest
x
in the direction of the current IEEE 754 rounding mode.
For finite nonzero arguments, the returned value is the requisite
whole number converted to type
long long,
if that is representable. Otherwise, the returned value is the
nearest representable integer value.
If the argument is a NaN, the result is the most negative integer
representable in type
long long,
errno is set to EDOM, and in IEEE 754 arithmetic, the
invalid
exception flag is raised. If the argument is finite, but the result
is not representable in type
long long,
or the argument is +Infinity or -Infinity, the nearest such
integer value is returned, errno is set to ERANGE, and
the IEEE 754
invalid
exception flag is raised.
