Re: : 80 to 64-bit FP conversion

Terry,

This is where you need to use the FROUND options in the FpMath-Config dialog
box. If you do a FROUND on a calculated 80-bit number, you end up with the
same value as if you stored it into a DFVARIABLE (aka FVARIABLE) and fetched
it back again. At least that is how it's supposed to work. ;)
