POPIS / INSTRUKCE

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.

NÁVRATOVÁ HODNOTA

The rounded integer value.

CHYBY / ERRORY

EDOM

The magnitude of x is too large and (math_errhandling & MATH_ERRNO) is non-zero.
