# linear-grammar: A simple grammar for building linear equations and inclusive inequalities.

This library provides some simple tools for building abstract syntax trees, representing linear equations and (inclusive) inequalities. As an example:

12x + 3y - 4z + 12 <= 43x - 7b + 8q

Would look like...

f = (12 :: Rational) .*. EVar "x" .+. (3 :: Rational) .*. EVar "y" .+. (-4 :: Rational) .*. EVar "z" .+. ELit 12 .<=. (43 :: Rational) .*. EVar "x" .+. (-7 :: Rational) .*. EVar "b" .+. (8 :: Rational) .*. EVar "q"

I've added some overloading functionality, to help ease the verbosity of the
above statements - an `IsString`

instance, and some other utilities. To pack
the equation into standard form,
use the `sandardForm`

function:

stdF = standardForm f
