While trying to track down a particularly elusive bug, I've come across something that I'm hoping is something stupid I'm doing.
Because if I'm right in what I'm seeing, ColdFusion can't count properly.
The situation:
<cfset Result = (val(1stNumber) / val(2ndNumber)) + val(3rdNumber)>
1stNumber = -5 2ndNumber = 0.3528 3rdNumber = 14.1723356009
ie: (-5 / 0.3528) + 14.1723356009
The result *should* be 0, or as close as makes no differnce.
The result I'm getting? -7.02904401351E-012
That is pretty close to zero! In fact much closer to zero than the ones where you've trimmed down the 3rd Number....
I've put up a page to test what I'm seeing, here: (http://devtest.formstar.com/test/a_calctest.cfm) I've put the code at the bottom of the output.
It's not until I trim the 3rdNumber down to 14.172 that I'm getting anything like a reasonable result.
I get the same results on both CFMX 6.0 and 6.1
Is it me? Is it CF? Is it an obscure setting I've overlooked?
