#7 BigDecimal instead of double

[Anonymous]

It would be great if BigDecimal were used instead of double, it would solve the famous 0.1 + 0.2 = 0.300...004 issue.

Currently,
new DoubleEvaluator().evaluate("0.1 + 0.2");
returns
0.30000000000000004

Yes, this would solve that issue ... and adds some issues on trigonometric functions (for example). Another way to solve the issue is to round the result.

Javaluator allows you to implement your own evaluators in a few lines of code, depending on what you exactly need. Examples are provided in the tutorial:
