MFC and Significant figures

[BluShu]

Alright my mission is to write a windows MFC program that prompts the user to enter 2 floating point values, and display their product. Sounds easy so far, however, the program must correctly handle significant figures and rounding. Is there any easy way to do this?? I am completly lost, and somewhat new at this. Any suggestions will help..

Thanks

The MFC CString::Format() function works a lot like printf(). Use a format string something like "%09.9f". The details are left to you to investigate... as a learning opportunity!

Check the format specifiers for printf() or CString::Format() in the MSDN library (if you don't have access to a CD, then go to msdn.microsoft.com and look on the menu for the MSDN library. It's all online).
