DESCRIPTION
These functions round their argument to the nearest integer value, rounding away from zero, regardless of 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. Note that unlike round(3), ceil(3), etc., the return type of these functions differs from that of their arguments.ERRORS
- EDOM
- The magnitude of x is too large and (math_errhandling & MATH_ERRNO) is non-zero.
