I actually got the problem wrong and still haven’t figured it out so here’s
another go.
I have a number which I need to encode as an RGB value each component being 4
bytes (12 bytes total) so I need to extract each digit as a byte (and then each
byte back to a digit). It’s basic low level compu

I don’t know why I typed this, each component is 1 byte obviously so each digit
can be up to 255 for a total value of 255,255,255? Not
I’m trying to pass a value between 1-1000 to an GLSL shader program which only
supports floats with a precision of 1 decimal place so the plan is to pack the
value into a vec4 (RGBA components between 0-1) which I could decode in the
shader program.
For example if I want to encode the value 50
