That's the idea, but not the source of my problem. The number I'm
looking at is larger than the maxInteger, which makes looking at the
remainder tricky.
Here are a few more details:
I've got a very large integer stored in a float, so I know it ends
with .0. If I divide by 2 and the result ends with .5, then I know it
was an odd number. I could convert to a string and look for ".5", but
thats cheating. :)
Here's some stuff from the msg window:
set f = 1144608783851.0
put f
-- 1144608783851.0000
put f/2
-- 572304391925.5000
Ideally, I'd just stuff the result into an integer and see if its
different than the original. Problem is it's too big.
set i = integer( f/2 )
put i
-- 2147483647
I suppose my question rephrased would be, is it possible to truncate
a float that is larger than the maxInteger?
