Precise Square Roots in Java

What is the best way to store irrational numbers like square roots in Java? I need a great deal of precision (over 100 digits), so float and double won't be good. Is it BigDecimal? I was using that before but I ran into strange problems, it could just be my code though. My code is very complex so I want to make sure BigDecimal is the right way to go before I rework the other stuff.

Solution

  • Check something like JScience it has a decimal class where you can set the number of digits and subsequently the required precision.

    something like this is what you need.
