This message is a programming error or a data input error.
Ask the program's author to fix this condition or to supply data in a different format.
This indicates an attempt to evaluate a mathematical programming function at a point where its value is not defined. The argument of a programming function in the math package is out of the domain of the function. This could happen when taking the square root, power, or log of a negative number, when computing a power to a non-integer, or when passing an out-of-range argument to a hyperbolic programming function.
To help pinpoint a program's math errors, use the matherr(3M) facility.
The symbolic name for this error is EDOM, errno=33.
