Are you sure there is anything being done in single-precision here?
You're right: Matrix Brandy uses double precision by default. If I really wanted to see this in single precision, I'd have to port it to MicroPython on a Raspberry Pi Pico.

It does seem a little counter-intuitive to me that adding the "#" suffix may actually reduce precision when using BBCSDL. I was also surprised that BBCSDL on aarch64 uses an extended-precision float format that has roughly 62 bits of precision where Intel extended has 63 bits.
