Yuck, that seems like a step backwards.
I learned from my FORTRAN days programming large statistical software packages on mainframes and minis to have great and abiding respect for floating point arithmetic, and moreover floating point comparison, and never to take things for granted. After all, as Leopold Kronecker succinctly stated "God created the integer, all else is the work of man".
