Question

I need to write a program that prints 0.(03) for input 1 and 33.
(1/33 = 0.03030303…. We use the notation 0.(03) to denote that 03 repeats indefinitely.)

As another example,
8639/70000 = 0.1234(142857)

I understand, I need to use an algorithm like floyds. But how do I get 0.0.030303030303 instead of 0.03030303030304 in java.

Answer 1

With this code, I think you’ll find what you’re looking for:

BigDecimal one = new BigDecimal(1);

BigDecimal thirtyThree = new BigDecimal(33);

//Fix the decimals you want, i.e. 21
MathContext context = new MathContext(21, RoundingMode.DOWN);

BigDecimal result = one.divide(thirtyThree, context);       

System.out.println(result);

This yields the next result:
0.0303030303030303030303
