[Boost-users] g++ warning: comparing floating point with == or != is unsafe

From: cybernet_at_[hidden]
Date: 2006-07-29 14:06:53

In:
    /usr/include/boost/test/floating_point_comparison.hpp

inside:

    template<typename FPT> inline FPT safe_fpt_division( FPT f1, FPT f2 ){

the warning is cause by the code:

       // Avoid underflow.
        if( f1 == static_cast<FPT>(0) || 
            f2 > static_cast<FPT>(1) && f1 < f2 * 
(std::numeric_limits<FPT>::min)() )
            return static_cast<FPT>(0);

Could someone modify the code to allow it to compile without warnings on 
g++?
Latest CVS version still has this problem.

I'm too dumb to think of a reasonable patch to submit - sorry.
