a -1.#IND problem

hello guys,

my program crashes, because some of the floats have a value of -1.#IND

i know it is a symbol for infinity and probably caused by overflow.

but my question is how to debug this error.

i want to add some lines in the code like:

if(value==-1.#IND)
...

therefore, i can identify the location where the wrong value is computed.

however, it seems that the compiler i'm using, which is visual studio 2008, doesn't recognize "-1.#IND"

so i don't know how to do this. please help. thank you very much.

You might have isinf() and isnan() functions available. Not every compiler does, but they're handy if you have them.....

If you are using Visual Studio, you can turn specific Exceptions on so you can catch it in debugger right when it happens.
