Re: Comparing floating point values in Java

I was calculating an array of float values from some user input. But sometimes (rarely) the calculation cannot be done (this is correct behavior).
I then want to mark these values by setting them to -1 and treat this special case later on. So I later need to test for -1 in my array.

Perhaps you can avoid the entire issue by choosing a
different "distinguished value." Float.NaN, maybe, using
the Float.isNaN(float) method instead of an == test. (NaN
seems a more natural surrogate for "does not compute," too.)
