What's the difference between function atof() and _tstof()?

[liuxianming2001]

CString a("2e3"); double b = atof(a); do right in VC++6.0 but wrong in VC++2008 CString a("2e3"); double b = _tstof(a); do right in VC++2008 but wrong in VC++6.0 :((

It all depends if either _UNICODE or _MBCS are defined. Please check out MSDN for more information on this topic. Regards, Mihai Moga

Thats the TCHAR mapping for atof/_wtof. By default vc2008 defines TCHAR as a native type. You can use it in vc6, you just need to do so explicitly.
