Question

I want to write some radian angles to a binary file. Is there any way I can save space while doing so?

I considered converting them to degrees and writing them out as a short but when converting to a short they loose their fractional part so that wasn’t going to work…

Any ideas?

EDIT: I only need 2 or 3 decimal points precision

Answer 1

There is a method from the Quake source code that writes them out as a byte like this:

((int)radian*256/360) & 255 //radian is the angle

Then reads it in like this:

b * (360.0f/256) //b is the byte read in

Which I tested and it leaves about 2 decimal places of precision, which should be okay for me.
