I would like to share a way to print all the digits of a number. The ResourceFunction ReadableForm will print all the digits. For example, N[96,2.54] displays 37.7953. I've stored the ResourceFunction in a paclet.
The helpful part about the ResourceFunction is that if I had a number with say 50 digits and I did NumberForm[number with 50 digits,40] then I would miss some digits, but with ReadableForm it displays all the digits by default.
