I vaguely remember hand-calculating binary approximations of floating point arithmetic
with pencil and paper, with a few left and right register shifts for scaling thrown
in, to demonstrate these issues during CompSci at university. They actually taught it
as a module.

Probably to make us aware of the dangers (or opportunities) of leaving computers to do
floating point arithmetic with large numbers, allowing white-collar crims (or
opportunists) to make a fortune off the missing rounding bit-errors.

'Course, that was a while ago now....

(One of my favourite employment filters for network ops:

How long will a gigabit ethernet router port at full utilisation cause the
byte-counter to wrap, if the byte-counter is a 96-bit register)
