Running ProC on AIX and have a oracle table
value stored as NUMBER and enter a value equivalent
to 2^32 (i.e. 4494267295) and when I select it into
a C variable defined as a float its precision
gives me a changed value (i.e. 4494267392)

Note change in blue. I need the value exactly as it is
entered. (trying to cast to longs fails as I think longs
on my system do not hold that large a number).

Any help appreciated.

Oops never mind...I made the wrong assumption
that floats had all the significance I needed.

Switched everything to doubles and I can
get what I want.

Rock on.
