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 non-zero.
