Rescaling an image with a factor from 0 to 1 does not work (arcpy.Rescale_management)

Question

Hey,
I am using ArcGIS Pro 2.5.1 and try to scale the CellSize of an image from 1 to a value of ~0.48 using arcpy.Rescale_management.

The Rescale - Data Management Tool in ArcGIS Pro works correctly for this use case

When trying to use the rescaling function in Python I get the following exception

If I export the function called in ArcGIS Pro as a Python script, the exact same function is called with identical parameters. Is there a bug in ArcGIS/ArcPy?

Edit:

It seems that only integer values are accepted or the decimal places are cut off.
1.488.. -> = scaling by factor 1, no Exception
0.488.. -> = 0?

From

Rescale—Data Management toolbox | Documentation

you will notice in the examples that they pass the numeric value as a string rather than a number

ie " 0.488 "

in your case.  This is indeed strange
