There are several public domain Forth floating point packages
available.  One is my floating point book from Mountain
View Press.  It is highly portable, but designed for
Forth-79 and not extremely efficient in the published form.
 
There are other floating point packages available elsewhere,
notably from the Forth Interest Group.  Be sure to get one
that does *not* rely on an 80x87 coprocessor if you want
to understand the guts of the operations.
 
At a more fundamental level, go to an academic library and
look up books on "computer arithmetic".

I don't speak for them, and they don't speak for me.
