Stepan,
Here is an example.
FindRoot[x == Cos[x], {x, 0.5},
AccuracyGoal -> 20,
WorkingPrecision -> 30]
{x -> 0.739085133215160641655312087674}
Ted Ersek's RootSearch package from MathSource is a robust replacement for
FindRoot and often more convenient to use.
Needs["Enhancements`RootSearch`"]
RootSearch[x == Cos[x], {x, 0, 2},
PrecisionGoal -> 20]
{{x -> 0.73908513321516064166}}

HI!
I'm using FindRoot to find root of some complicated algebraic
equation:
FindRoot[zero, {Beta, Beta0}, MaxIterations -> 200]
> {Beta -> 18.7129}
It works fine and the result is right. Though it shows only 4 digits
of the result, rounding the number. But I need to see first 20
digits. Yes, I can press space and Mathematica will show the whole
number, but I want to know how to do it in place.
