will tell you that it can't be converted to an integer.
Go figure.

Well, "01234567890" _is_ an integer, unless the rules have changed. Maybe
it's too big for the mod function, though; CF can't handle large numbers (I
don't remember exactly what "large" is). How about either
val(form.myField) MOD 100
or
cfif len(form.myfield) LT 6 !---maybe not six,
Use the IsNumeric function to test for a number value, then perform your
MOD stuff
Hopefully someone can shed some light on this. I've got a field where I'm
looking for an integer. I then need to verify that this field is in an
increment of 100:
cfif form.myField Mod 100
It's not an
Try this:
CFIF IsNumeric(myformfield)
CFSET newint = Int(myformfield)
CFIF newint MOD 100
not an integer

/CFIF

How could a number "01234567890" be an integer? It's not even a real number!

it appears that coldFusion can't handle very large integer. one work around
solution is to check for the last two digits being "00". if they are, the
integer is divisible (or increment of) by 100. here's the fix:
cfif isNumeric(form.myField)
cfset rightTwoDigits = right(form.myField, 2)

definitions vary.
All Numbers

value in some engineering fields, and in mathematics. What number, when

Huh? Do you mean because of the leading zero? Most of the time computers
can ignore that. What else makes it not an integer? If I write it as
1,234,567,890 is it an integer?
Not wanting to fight, but curious..
