Help Notes

Tabbed Browsing

The Calculators have been built with an effort to allow logical tabbed navigation through the entry fields to the "Calculate" button. So, on most calculators you should be able to enter information frow left to right and use your tab key to move to the next field then to the "Calculate" button and hit "Enter".

NaN

Not a Number. You entered a value that can not be operated on or there does not exist an answer for your calculation.

Inf

Infinity. The answer is beyond the abilities of the php engine that is used to make the calculations. Generally the limit is 10^300.
