NAN with floating point values means "not a number", that is you get
a combination of bits that don't make up a sensible value. Check
the UDF directly (assuming you have the sources), there seems to be
a little glitch in there (precision mismatch, division by zero or something?)


when parsers parse, and compilers compile, then why don't objects object?
