'function' : _SING error
An argument to the given function was a singularity value for this function. The function is not defined for that argument.
For example, in FORTRAN the following statement generates this error:
result = LOG10(0.0)
This error calls the _matherr function with the function name, its arguments, and the error type. You can rewrite the _matherr function to customize the handling of certain run-time floating-point math errors.
