How to work with Digits higher to 50 in all the document

Hi all,
How to set Digits higher to 50 (i.e. 110) in all the document and calculations.
For example, I want to set Digits=110; and do all my code with this number of Digits ?
Thank you

Have you considered if SetPrecision will be sufficient. A tutorial with a larger scope is found in tutorial/NumericalPrecision. Hope it helps.
