CF 6.1 is wrong when performing BASIC math operations!! - Coldfusion - Advanced Techniques

try this: <cfoutput> <cfset calc=652.06 - 652> #calc# </cfoutput> The result should be 0.06, but CF returns 0.0599999999999 ! Does anybody know a workaround?...

    Default CF 6.1 is wrong when performing BASIC math operations!!

    try this:

    <cfoutput>
    <cfset calc=652.06 - 652>
    #calc#
    </cfoutput>

    The result should be 0.06, but CF returns 0.0599999999999 !

    Does anybody know a workaround?

    Not sure why it would do that, but it does it in CF4.1 as well. Try
    this:

    #Evaluate(Round(calc*100)/100)#

    I'm guessing that since CF is Java-based, a decimal value is stored as a float
    value, which has so many bytes. Additionally, essentially, 0.0599999999999 =
    0.06...that's pure Math, and I don't remember any of that, but take my
    word...it is. :-)

    Hope that this helps. Thanks.

    <cfset calc = (((652.06*100) - (652*100))/100)>
