There is method unless some reference from source.
Some solvers work more accurately then others.
Generally, they will range from 4 decimals to 15 decimals.
Some functions are so involved in numerical error propagation
that you will have to refine the search range ... Goat radius.

Yes, using a initial values more accurately I have a better precision. Thanks so much

Another example, much different solver.
15 decimals in Engineering works makes no sense
Cheers for your profitable application(s) ... Jean.

... both high accuracy solvers in same document.
Your stuff collapsed/disabled.
Occasionally, roots(2), roots(3) are profitable.
