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

cybernet@interia.pl writes:

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++?

Try replacing f1 == static_cast<FPT>(0) with f1 HTH, -- Dave Abrahams Boost Consulting www.boost-consulting.com
