nidl.metrics._regression._find_matching_floating_dtype(*arrays)[source]¶

Find a suitable floating point dtype when computing with arrays.

If any of the arrays are floating point, return the dtype with the highest precision by following official type promotion rules:

If there are no floating point input arrays (all integral inputs for instance), return the default floating point dtype for the namespace.
