Whoops. The answer needs to be a number, not a string.

Admittedly, I know very little about Java but I'm suprised this work since I can't find a constructor that takes a double. Only strings, byte patterns or random number generators. Care to explain?

Clemens Giegerich on 2 Jul 2014

There are a constructors for int and double: http://docs.oracle.com/javase/1.5.0/docs/api/java/math/BigDecimal.html#BigDecimal(int)
http://docs.oracle.com/javase/1.5.0/docs/api/java/math/BigDecimal.html#BigDecimal(double)

Oh yes, I missed that you were using BigDecimal instead of BigInteger.
