[bug] Number format in CAS

[Tugdual]

I used Stats 2 vars to calculate a fitting curve.
Then I copied the equation into CAS. The equation has constants written with the chosen number format (comma for decimal places and space for thousands) but CAS is not able to read the constants. I noticed that CAS seems to ignore the chosen number formats.
What is the right way to proceed?

Store the constants used in variables and use the variables in your CAS work?
