I've been poking about....
It looks like Frac32 aka Q5.27 is the preference for fractional values.
That's a choice, particularly for a machine without an FPU, but this platform has one, and so far as I can tell it's performance is comparable to the int operations and involve less mucking about with shifts, saturation, etc. You lose a few fraction bits going to single precision float, but code clarity is improved (IMO).
Then there's the interesting case of the mutable modules where Q5.27s are converted to and from a float on either side of the call to the mutable code.
So is there any thought to having a FloatBuffer type to connect objects?
You could even do implicit conversion and allow direct connections between Frac32 and Float types
I apologize if this is a fixed/floating point religious issue, I'm just trying to avoid the cognitive load of shifts, SMMUL, SMMULA, etc.
