FracCalc is a calculator for performing simple arithmetic operations with fractions. This is the fraction calculator application from Programming in Objective-C 2.0, by Stephen Kochan. The calculator is based on Program 21.2 from Chapter 21 of that book, with enhanced features as described in the exercises at the end of the chapter. Most notably, a CVN key is added to convert fractions to decimals, operations can be chained, and they can be continued after the Equals key is pressed.

The source code for this application is available for download at the forum for the book:

Performs as advertised

Simple, works. 'nuff said.
Idea 1: If I enter a fraction and press =, please reduce to lowest terms.
Idea 2: If a decimal number is being displayed and CVN is pressed, convert back to a fraction, and allow more calculations. In conjunction with this change, in case you want to start from a decimal number, allow entry of a decimal point.

Quite the divisive app!

Although I don't deal in fractions often, this is so useful just to help reassure me when I need to use them. My son will really benefit by using it. Thanks for the gift!

Can't use whole numbers?!!?

Glad I didn't pay for this. Seems stupid without the ability to use whole numbers in equations
