Get exact curve parameters in the fit function

Hi,
I have created and saved a cfit object using the fit() function.
How can I access the exact values of the coefficients? By exact I mean for example coefficients with 10 decimal places.
I am aware that I can access the coefficients using coeffvalues(fitobject) but this only gives the values with 4 decimal places. I am also aware that I can evaluate the fitobject for new data to get the exact result but this is not an option for me, I need the exact coefficient values for the use in an anonymous function.
Any help is appreciated

Ran in:
The four decimal places are just the default display value. You can change that with the format command. For example, use format long before calling coeffvalues(fitobject).
pi
ans = 3.1416
format long
pi
ans =
3.141592653589793
Alternatively, just store the value in a variable, and use the variable in your anonymous function.
