    Coldfusion 8,9,10 errors during simple calculations

    PawelDulak

      We found strange issue during simple calculations. When trying to calculate:

       

      1089.11 + 97.63 - 1186.74

       

      we are receiving:

       

      -2.27373675443E-013

       

      but this value shoud be 0 (zero). Please try the following in your CF:

       

      <cfoutput>

      #1089.11 + 97.63 - 1186.74# (should be 0)<br />

      #1079.11 + 97.63 - 1176.74# (should be 0)<br />

      #1079.11 + 107.63 - 1186.74# (should be 0)<br />

      #1189.11 + 97.63 - 1286.74# (should be 0)<br />

      #1089.11 + 97.63 - 1186.64# (should be 0.10)<br />

      #2089.11 + 97.63 - 2186.74# (should be 0)<br />

      #3089.11 + 97.63 - 3186.74# (should be 0)<br />

      </cfoutput>

       

      It's strange and we are not sure how to deal with this issue. Of course we can use Round, we can use some other methods, but we don't want to review all our applications to check if such situation occured...
