A simple command line program for solving the quadratic equation. I built this purely to save me a little time when doing algebra for my engineering homework. The quadratic formula shows up quite often in circuit problems for non-linear circuits, and it becomes tedious to evaluate the quadratic formula each time.
To see usage instructions for this program, please run quadratic -h.
Example output:
[user]$ quadratic -- 1 -10 16
1.000000x^2 + -10.000000x + 16.000000
x = 8.000000
x = 2.000000
[user]$ quadratic -v y -- 1 -10 16
1.000000y^2 + 2.000000y + 3.000000
x = -1.000000 + 1.414214i
x = -1.000000 + -1.414214i
The build recipe is in the Makefile. Running make all will create a binary called quadratic which you can then run.
Although only tested on Linux, this program should build and run just fine on all other platforms.
