Double precision computation

[GOdin.1]

I'm using STM32F446xx 32-bit MCU, but I want to do computation using double precision. Is it possible to perform double computation precision using given MCU? And if so, how can I make sure that double computation is performed?

the compiler doing this for you - always.

if you use "double" variables.

STM32F76x has FPU HW 64 bit.
