convert 32 bit float in 64 bit float

Good morning.
If a variable declared as float exceeds the maximum positive limit, adding the value 1 changes its sign to negative. Is there a component that can manage the saturation of a float variable even after its saturation in both positive and negative directions?

All HAL float pins are 64-bit doubles.

Are you needing to deal with Single precision floats from something like Modbus or EtherCAT.

In the general case there is no way to do this, as there is no way to know what was intended. But if there is an assumption that the value is approximately continuous then you can make an inference.

That said, it's hard to think of any engineering quantity inside a CNC controller that could overflow. (encoder and stepgen integer counts potentially can)

Also, I don't think that your initial assertion is correct:
