Why does 0.06 + 0.01 = 0.07 in ColdFusion?

Question

Why don\'t math operations in ColdFusion seem to be affected by floating point math issues? Take the code:

result = 0.06 + 0.01;

writedump(result);
writedu         


        

Answer 1

I strongly suspect it's simply rounding differently on output. In other words, the issue is still there - it just happens not to show up when this particular value is printed out with writedump.

What happens if you use:

writedump(String.valueOf(result));

?
