Remarks
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. |
