> "Q16.16" seems to refer to fixed floating point precision

Floating is the opposite of fixed in this context. The GP is unhappy that it doesn't support fixed point numbers of a common fixed point number format.

This is not just nitpicking, because the difference in time and implementation cost between floating and fixed point can be huge on systems where floating point operations aren't offloaded to a pipelined FPU. Fixed point arithmetic on the other hand, even if your hardware doesn't support it directly, can easily be implemented in terms of integers.
