Because it is money I need to int/trunc/floor the value. -----Original Message----- From: Barney Boisvert [mailto:[EMAIL PROTECTED] Sent: Monday, December 12, 2005 5:32 PM To: CF-Talk Subject: Re: Is this a bug in CFMX?
Don't use int(), use round(). int() truncates, and is equivalent to the floor() (the inverse of ceiling()) function found in most languages. round(), on the other hand, follows normal rounding rules (0-4 goes down, 5-9 goes up). cheers, barneyb On 12/12/05, Shawn McKee <[EMAIL PROTECTED]> wrote: > So if I need to accurately convert a floating point number with X digits in the decimal portion to one with Y (Y < X) digits what do I do?
