I am having an intermittent problem. It's a C++ program written in VC++ 6.0 (very old, I know). It's a fairly complex application with some fairly complex mathematical calculations. Most of it wasn't written by me. Anyway, every once in a while one of the fields on the screen shows "1.#QO" instead of the proper result. This MIGHT be just the beginning of the string, because of the size of the field is limited.
I am sure it's a bad calculation somewhere that probably results in an invalid floating point number. Does anyone have an idea that could help me narrow my search?
