That comes out as 3.0517578125000000e-005. Wish I payed more attention to maths back in school. Right now I'm trying to find out what that e-005 means.

WalderMight now I'm trying to find out what that e-005 means.
It means 10^-5, i.e.
3.0517578125000000e-005 = 0.000030517578125000000

Thankyou thankyou thankyou. I have been on google for the last hour trying to find the meaning of that, but every page seems to think it's a universally understood system, kinda makes me feel stupid 
Anyway, my code is now working. Thanks for the help guys

Thanks for the link, but the 'great firewall of china' prevents me from accessing wikipedia

You should probably be using double constants (e.g., 1.0, 16.0), so that the math library is properly initialized.
BTW, your name wreaks havoc in the Quote Selected Text feature. It inserts a malformed </b> tag.

That's exactly what I was doing wrong, but that exponent was giving me a real headache, I thought the wrong values were coming out. I hate floating point maths!

Hello everyone,
Are there some formal documents about which physical files contain C++ related libraries' implementation on Windows (i.e. something like mscvp*, to run and build C++ application, all required static lib, import lib and DLL)?
How about the physical files for C (i.e. CRT) and for all Windows API?
BTW: maybe my question should be asked in another way -- the frequently used DLLs (like user32.dll) and related functions, import libraries and static libraies for Windows platform?
thanks in advance,
George

No. And if it they did exist you certainly would not find them on the Microsoft web site.

Why you dont use of tools for check dlls that your program is using them.
