RE: Integer?
You missed a previous message where I stated that isNumeric() will return
true with any string that contains (0-9) i.e. ReFind("(0-9)","012345678") is
identical to isNumeric("012345678"). However, try using "012345678" with the
Mod operator, and it will tell you that it can't be converted to an integer.
Go figure.

I have CF 4.5.1 and this statement simply isn't true. IsNumeric()
returns a true no matter how many 0's prepend a number, as long as the
number is a number. Maybe in earlier versions of CF it returned a
false, but if it did I am not aware of it.

it can't be an integer...
Anyone know what the maximum size for an integer in CF is?

RE: Integer?
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).

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.

RE: Integer?
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) cfif rightTwoDigits IS NOT "00" It's not an increment of 100! cfelse yes, it is /cfif /cfif -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 11, 2000 6:56 AM To: [EMAIL PROTECTED] Subject: Integer?

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.. The previous poster is incorrect. "01234567890" is indeed an integer. The computer of course ignores the leading 0. CF's precision will only go up to (12 digits) and then it starts using scientific notation.. (1.23456789012E+012). So, if you want to handle numbers over a trillion precisely, you'll have to do some creative programming. Also, beware the commas.

RE: Integer?
I'm going to lay out what numbers are what. For programming purposes these definitions vary. All Numbers Imaginary: Numbers that do not exist for practical purposes. They have real value in some engineering fields, and in mathematics. What number, when multiplied with itself gives you a negative result. That would be an imaginary number. Real: All numbers that are either negative or positive. No imaginary numbers are real numbers. Rational: All numbers that can be put in fraction form. Irrational All numbers that cannot be put in fraction form. Integers: All numbers that do not contain a decimal point Whole: All numbers that are integers and are not negative Natural: All numbers that are integers and are not negative and are not zero. -- Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=listsbody=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.
