  1. The symbol “Pi” is always the ratio of circumference to diameter by definition. Your projection of “Pi” into a floating point number of arbitrary precision is the issue that invalidates your blurb. Solve your equations symbolically when handling irrational numbers, and you’ll be fine, don’t worry.
