Working on a novel (hopefully!) floating-point format for my custom CPU #ISA . It doesn't have any floating point operations -- as a matter of fact, it only has 16 operations ("instructions") -- but I'm working on a floating-point format optimized for software emulation on it.
That said, I already have in my stdlib macros for fixed-point #math (Q16.8 format), as well as a sine function and sqrt function.
OK -- I finished a prototype for my custom mono-field floating-point format, in Golang. I haven't done extensive testing, but it works fine so far -- addition, subtraction, multiplication, and division.
One of the distinguishing characteristics of it is that the amount of bits *available* for the significand varies based on the exponent. You get between 0 (yes) and 32 (yes) bits for the significand.
I think I'll put this up on #GitLab at some point.
