Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
All functions shown above: _XOPEN_SOURCE >= 600  _ISOC99_SOURCE; or

DESCRIPTION
These functions round their argument to the nearest integer value,
using the current rounding direction. If x is infinite or NaN, or if
the rounded value is outside the range of the return type, the numeric
result is unspecified. A domain error may occur if the magnitude of x
is too large.
RETURN VALUE
The rounded integer value.
ERRORS
EDOM The magnitude of x is too large and (math_errhandling &
MATH_ERRNO) is nonzero.
CONFORMING TO
