That required simulating decimal

easier to get correct rounding on zillion dollar financial calculations it
could well be worth the cost.
Why? Double precision gives you 15 digits. That is Elon Musk calculating his wealth to the exact cent. Were there enough cents saved to pay for all that extra coding effort?
