Plot inverse of emulated double-precision floats
I need to accurately plot a line chart using WebGL. The numbers have a precision of around 33 bits - that's too many to fit into a single-precision float's mantissa. WebGL does not support the double-...

Floating Point Operations in Line Drawing Algorithms
When it comes to line drawing, DDA is the simplest and most intuitive algorithm, the core idea being:
compute the slope of the line
for every increment in x, increment y by the slope
However, DDA is ...
