FPU specs for M7 & M4 on GIGA

Official Hardware Mega GIGA R1 WiFi

Hello,

Since there are several variations of M7 and M4 (for FPU support), may I get a link to any Arduino documentation that provides the specs for the FPU units on GIGA.

Presently, float and double are running at the same speed (in my newbie/beginner sketches). Perhaps my code is buggy. There is no noticeable difference in the speeds for M7 & M4 for FPU but there is clearly some for int/long math.. I simply need some reference documentation. No issue regarding speed for my use cases. Thanks.

Regards.

You might check whether the compiler used by the Arduino IDE supports the FPU, and if so, whether that support turned on by default.
