Hi,
How can I specify the precision a static text element in a GUI displays?
I use "set(handles.result,'String',result)" to set the value to the static text element but it only shows 4 digits.
I'd bet there is a very simple way to set the number of digits. Does anyone know how to do that?

Your variable 'result' must be a string. If you use num2str(), the default precision is 4 digits, such as num2str(pi) shows 3.1416. You can use num2str(pi,'%20.10f'), or you can use sprintf().
