 yehyeh! duUuuh, *now* it sinks in?? :)  you're the one that wanted
 to implement floating-point, ya muppet!

 ... starts to make sense what jacob was saying about hardware
 not supporting 2 ** 0.5?

 just keep iterating and exploring, ok? not sure of something, simply
 write a small bit of code to check if it's true.

 the faster you can do that, the quicker you'll understand, and the
 quicker you can write the code.

 i regularly (like... 15 times a day) run python3 interactively just
 to do some exploring, not even write some code, just type directly
 at the prompt.
