Hi

I use scalars to solve a (simple closed form) quadratic equation. Nevertheless, they always give a 6 digits precision (a float). I tried to declare the scalars as doubleScalar instead of just scalar. However, the result is still in 6 digits. I made sure that the solution can be more precise http://www.mathsisfun.com/quadratic-...on-solver.html
