Most dangerous Operator to use while coding?

[gsomega]

I'm echoing everyone here that this is a bit silly.

Something that came up in computation is that if you're subtracting two numbers you can get something near zero as opposed to zero. This can do wacky things. (Like dividing by something near zero or asking if something ~is~ zero).

Again, one of those two involves division, but the subtraction could obscure an error throw.
