I was wondering if there was a nice way to combine two float point variables and use it like 1 float point variable with extra precision.
The purpose is for use in a GLSL shader where I would like to have more precision in the calculations. (Fractal Zoom). The version of the shader language I used had access to float point numbers but no integers.
The operations I need on the higher precision float point number are just additional / subtraction & multiplication.
