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 Result is too large to be represented in function's return type.
_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.
