Oh god, it appeared without description, sry.
So my problem is that I've made the Regression(l1, f)
Where l1 is list of points and f(x) = ax^3+bx^2+cx+d
Geogebra draw for me a graph of new function and the equation with some numbers.
I wanted to check this so I've made another function with a,b,c,d set on numbers showed in regression function.
I was suprised that graphs aren't the same and after manually checking it was obvious that numbers showed in regression equation aren't precise enough.
Is it a bug or is there any way to get fitting numbers?
Please post your .ggb file

Yes, that was indeed the rounding issue. An extremely useful tip, thank you!
