[net.micro.cbm] again: floating point problems.

Thanks for the answer, but I'm not quit satisfied yet.

How do you store a floating point number in a look-up
table?

For instance the number 234876.3129765 ???

How many bytes do you need to store it and how do the
bytes look like in memory?

I hope someone can give me an example of simple
arithmetic with floating point numbers.

				Thanks already,

"Inside the VIC-20" by Nick Hampshire has a very thorough treatment
of floating-point for the Commodore machines, including ROM addresses
to access the BASIC floating-point routines.  The BASIC in the VIC-20
and C64 are identical (except one starts at $C000 and the other at
$A000), so the book applies equally to both machines.
