ntegerOperations

Hi!

I'm very glad someone is willing to address this problem, which seems
to be neglected. ;-)
  
You might want to take a look at SafeInt:

e/html/secure01142004.asp
It takes a different approach, which IMO is more convenient in most
situations than the free functions, it defines a wrapper class
template which controls all the arithmetic operations of the
underlying type. The code is copyrighted and highly
platform-dependent, but I think that if Boost is going to have any
arithmetic operations checking mechanism, then it should rather look
like this.

Also, I think the interface containing a bunch of C-style set of
functions with arguments' types pushed into the functions' names is a
bit inadequate for a modern C++ library - it makes it very difficult
to use your library in a generic code, and it makes it easy to perform
unwanted argument conversions.

Best regards,
Robert
