problem with compiling C code in VC++6

First of all, I am a newbie, so please be gentle to me ;)

I am trying to run a set of codes (written by sb else and tested OK) in VC++6. I get the following error:

"fatal error C1083: Cannot open include file: 'nan.h': No such file or directory
dataSet.C"

anybody could help plz?
what is nan.h?

It sounds like a header that contains functions to deal with NaN floating point values.

It also sounds very non-standard, so you should contact that somebody else and ask them where they got it.

Finally, VC++6 is incredibly outdated, and you can get many far better compilers for free, for example Visual C++.Net 2008 Express, or Visual C++.Net 2010 Beta 1, or MinGW in the nice Code::Blocks package.

thanks,

I tried to contact him but he is nowhere to be reached! Thanks anyhow! I 'll keep looking
