# A Fraction Calculator

for Woodworkers

*(and anyone else needing to do fraction calculations)*

## an iPhone app

This app came into being because Jim's fraction calculator was beginning to show signs of functional abuse (i.e., it's tough living with the dust in a full-time woodworking shop).

## Using the Calculator

The calculator works like a simple decimal calculator, except that it allows and presents numbers as fractions. When entering whole numbers only, you can override the fraction mode by adding a decimal point to one of your numbers.

Entering fractions is a two or three part process:

### Entering a three part fraction like 1 2/3

- Tap the One (1) button. The number '1' is displayed.
- Tap the Fraction (a b/c) button. A dot (•) is displayed.
- Tap the Two (2) button. The number '2' is displayed after the dot.
- Tap the Fraction button again.
- Tap the Three (3) button.
- The fraction displayed will look like this:

1•2•3

- After tapping an operator key ('+', '-', etc.), the fraction looks like this:

1 2/3

### Entering a two part fraction like 4/5

- Tap the Four (4) button. The number '4' is displayed.
- Tap the Fraction (a b/c) button. A dot (•) is displayed.
- Tap the Five (5) button. The number '5' is displayed after the dot.
- The fraction displayed will look like this:

4•5
