Re:probably a dumb question about atm and cents (Score 1)

But does any one know why atm's here in the states have a decimal in the amount?

The reason why? Its to minimize the negative effect of user error. I've always thought about it like this: Regardless of what is displayed (users don't always read) some people will assume that they enter in just dolars, and others will assume they enter it in dollars and cents. If want $20 and you enter 2-0, you'd get back either $20, or .20. Most likely the .20 causes an error and tells you to retry. However if you enter 2-0-0-0 (similar to how you'd write it on a check), depending on the machine you'd either get back $20 or $2000! And what the heck do you do standing in the middle of the street with $2000 in hand? So bank accts have max withdrawal limits in cash of only a couple hundred, but many don't.
