I'm not sure what you mean by "string" everything, unless that was a typo for "strip". According to the docs, int is supposed to return then the next smallest integer. So technically it doesn't even "strip" as -4.3 would return -5.
If you pass in an even integer, it should come out unscathed. It appears in my example; the integer 6 is being stored behind the scenes as a double and being secretly (and inconsistently) rounded for me. ~Brad -----Original Message----- From: Greg Morphis [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 06, 2008 6:02 PM To: CF-Talk Subject: Re: CF redefines math: 5 = 6 Doesn't int() just string anything after the decimal away? so 5.99999999 would be 5? rnd(5.99999) would be 6. ceil(5.9999999999) would also be 6.
