Floating point


Recommended Posts

In the 80's there was a CPU called a Transputer that had a floating point representation that was always between -1 and 1 as a 16 bit entity. What was special here is that there were no rounding errors. I believe the multiply operation was called FRACMUL. It was used for 3D rotations of planes at a MRI unit I worked with. That kind of "floating point" would be very nice to have for 3D math on a Lynx at least.


7FFF * 7FFF = 7FFF in that world as 7FFF = 1.0. Does anyone have an implementation for that for the 6502?
