Implementing [a computation]
on [a processor]. Fixed versus
floating point: precision,
speed, silicon cost, where
rounding accumulates. Recommend
one and show the reasoning.

Fixed Point or Floating Point?

Where the rounding accumulates, which usually settles it.

Prompt

I'm implementing [a computation] on [a described processor]. Compare fixed and floating point for it — precision, speed, silicon cost, and where rounding would accumulate — and recommend one with the reasoning shown.
