The RPG Reference V5R2, Chapter 10 (Data types and formats) page 186:

"Note: Float variables conform to the IEEE standard as supported by the
OS/400
operating system. Since float variables are intended to represent
?scientific?

values, a numeric value stored in a float variable may not represent the

exact same value as it would in a packed variable. Float should not be used

when you need to represent numbers exactly to a specific number of

decimal places, such as monetary amounts."



I realise that this isn't an explanation of why the results are different
between V5R1 and V5R2.  It does seem to be a disclaimer that we shouldn't
expect float to be terribly precise, which is a different attribute from
repeatable.  I apologise for the non-web manual references; I keep the PDF
on my desktop and frankly it is far easier for me to crack open the book
than to surf the web.
