How do you go about poking decimals into memory? I just need about 3
decimal places of precision.

Oh, duh. Thanks for your help, again.

Using poke4(address, number*1000) and (peek4s(address)/1000) will get you
a fixed precision of 3 decimal places, at the cost of reducing the whole
number part of the decimal by the 3 uppermost decimal places that a 32bit number
can represent ... you probably don't need to worry about this, and if you do
then you are better off using 64bit floating point instead of fixed precision.

That makes a heck of a lot of sense. I think my brain is on an extended
vacation. The built-in atom_to_float32 works wonderfully, too. (Thanks
Brian Broker)
Thanks for the suggestion. I should probably go to bed now, but I'm
having too much fun!
