Problem Note 13464: Floating point equality comparisons inaccurate
Floating point calculations do not always produce expected results.
For example:
39 * .1 = 3.9 Does NOT work
9.3 * .1 = .93 Does NOT work
3.1 * .3 = .93 Does NOT work
.93 * .1 = .093 Does NOT work
.67 * .14 = .0938 Does NOT work
.73 * .133 = .09709 Does NOT work
.798 * .123 = .097047 Does NOT work
.12187601 = .12187601 Works
.31 * .3 = .093 Works
