You do not have to move at all, as the title suggests. You do not have to enter your dollar amount with a decimal (You can, though). Also, DO NOT enter your dollar amount with a dollar sign. And you can't go above $999.99. (Also please let me know if there are any bugs.)
I just wanted to help people with money if they needed it. I got this idea from my mom's tip calculator on her iPhone. Here is the link: http://bigblueclip.com/portfolio/free-tip-calculator And feel free to remix. (But I don't really know how you could) New in 4.0... There are now discount settings like a 20% off. *Please do not put the percent sign when you do the tax or discounts.
