I know about a BigDecimal class in Java, but I don't know about anything like that in Perl

Math::decNumber provides arbitrary precision decimal arithmetic.

    OK, thank you, I had not heard about that module before.
      And installing Math::decNumber is as easy as:
      cpan -i Math::decNumber
      There's no need to worry about first locating and downloading the decNumber library as it ships with the module - and the functionality is automatically built into the Math::decNumber dll/so as part of the build process.

      All very easy, passes its test suite, and works well:
      C:\> perl -MMath::decNumber="d_" -le "print d_(0.3) - d_(0.2) - d_(0.1 +);" 0.0 C:\>perl -MMath::decNumber="d_" -le "print sqrt(d_(3));" 1.732050807568877293527446341505872

      No trig functions, unfortunately.

      Cheers,
