Hello the question is. Is it possible to make, that every time function antan returns in degree?
example:

atan(0.2/0.75)=0.343 every time I must add units "deg" that it returns not in radians. Maybe is possible to safe time and make change somethere in software. Thank You for the help

You can override atan() function.

Personalize like this as an utility at top of work sheet
to avoid conflict with the atan(x) built-in from Windows library.
Atan(x):=atan(x)*360/2*π
Atan(4)=75.964 then by personalized 75.964°.
