@ccollins476ad since e.g. Cortex-M4 has (optional) FPU which supports single precision operations, on those MCUs `double` will be converted to `float` in sw and then calculations will be done by FPU so there will be some performance gain here. And I agree that this should be conditional on syscfg setting so we do not break standard in default configuration.
