In an acronym, ILE.  Floating point numbers are the "normal" decimal number
format in C (C on the 400 must support BCD, but I'm talking "regular"
library functions.)  If you look at the ILE math APIs you'll see all sorts
of float parameters.  Floats give you the chance to use APIs and things from
other languages that you couldn't touch before.  For a lot of business
programming, you'll probably never use floating point numbers.  I know I
haven't except in playing around with them.  
It's nice to know that they're there.
