Simple command line calculator.

gcc src/calc.c -lm -o calc

gcc src/calc.c -o calc.exe

calc <equation>

Currently Supports: powers, division, multiplication, addition and subtraction (see issues for roadmap)

N.B. Use x rather than * for multiplication, or surround the whole argument in speech marks: "<equation>"

Windows Notes:

• Use ' rather than ^ for powers, or surround the whole argument in speech marks: "<equation>"
• Substitue ./calc for calc.exe below

Most simple usage of calc(n):

$ ./calc 1 + 1
= 2

Precedence is correctly respected:

$ ./calc 2 + 4 x 50 + 2
= 204

Powers also work

$ ./calc 2^3
= 9

A few constants (e, pi and phi) are built in:

$ ./calc 2 * pi
= 6.28318530717959
