An0n, I had started from scratch and then discovered the script you linked to and modified it, but the limitation I’ve given above emerged.
I got to the point of having a script that gave me power of two times in seconds, which is not precise enough. Any other solution working with fixed point were either too cryptic to use or would require a pocket calculator to convert to human values. I didn’t want to look at implementing fixed-point math.
Thanks, fudgey, BTW.
