And yes they have fp units. For doubles! From the 4.0 page, which has the
same chip: "Teensy 4.0's Cortex-M7 processor includes a floating point unit
(FPU) which supports both 64 bit "double" and 32 bit "float". With M4's FPU
on Teensy 3.5 & 36, and also Atmel SAMD51 chips, only 32 bit float is
hardware accelerated. Any use of double, double functions like log(),
sin(), cos() means slow software implemented math. Teensy 4.0 executes all
of these with FPU hardware."
