Math Error Constants

#include <math.h>

The math routines of the run-time library can generate math error constants.

These errors, described as follows, correspond to the exception types defined in MATH.H and are returned by the _matherr function when a math error occurs.

Constant

Meaning

_DOMAIN

Argument to function is outside domain of function.

_OVERFLOW

_PLOSS

Partial loss of significance occurred.

_SING

Argument singularity: argument to function has illegal value. (For example, value 0 is passed to function that requires nonzero value.)

_TLOSS

Total loss of significance occurred.

_UNDERFLOW

Result is too small to be represented.
