calculators

Yeah, dorky. These are some calculators I coded, if you use them please get a second opinion, as I make no claim to their accuracy. I created these because I found myself using other javascript calculators far too often. The ones I would use were either horribly designed and impossible to use, or were coded rather poorly.
