fCalc

Command Line Fractional calculator using Swift

How it works?

The command-line program will repeatedly prompt the user for input and display the result until user types “exit”.
Legal operators shall be *, /, +, – (multiply, divide, add, subtract).
Operands and operators shall be separated by one or more spaces.
Mixed numbers will be represented by whole&numerator/denominator; for example, “3&1/4”, “-1&7/8”.
Improper fractions, whole numbers, and negative numbers are allowed as operands.

Example runs (where ‘?’ represents the command prompt): ? 1/2 * 3&3/4 = 1&7/8

? 2&3/8 + 9/8 = 3&1/2

? 1&3/4 – 2 = -1/4
