Since I'm old enough to have learned Physics on a slide rule, and programming was strictly done with Integers a decade later... Then the 'Pentium Math Bug' hit the news to show that Floating Point / Real Number math had a basic flaw, I learned not to trust any Floating Point math without a 'Sanity Check'...

I still use Integers for 99% of my programming, and imply the decimal places with Tag Names like PSI_X100
