Bad Math??!!?

Unfortunately, this calculator can’t do math… and as that’s the only thing I need it to do… needless to say, it didn’t work out.

617.14 minus 602.45 does not equal 14.689999999

Close, but not close enough.

Works Great, But the updates!

I cant tell if this app updates more than the news or what! Seems like theres always an update daily, and it's the same version every day! What gives?
