Error while dividing BigDecimal value : java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result

Question

I have refer this and did rounding of BigDecimal value then also I am getting above mentioned error. Please find code mentioned below. Thanks in advance:

BigDecimal val1 = new BigDecimal(494.10000001).setScale(8, BigDecimal.ROUND_UP);
BigDecimal val2 = new BigDecimal(693189.38625000).setScale(8, BigDecimal.ROUND_UP);
BigDecimal result = val1.divide(val2);
System.out.println(result);

try BigDecimal result=val1.divide(val2,8,RoundingMode.HALF_UP); — Amit Bera, Feb 17 '18 at 08:53
The post you linked mentions `a.divide(b, 2, RoundingMode.HALF_UP)`, but that's not what you're doing, so I'm inclined to say this is just a duplicate of that, or a typographical error. — Bernhard Barker, Feb 17 '18 at 09:06

The answer was in that post, and stated multiple time also:

a.divide(b, 8, RoundingMode.HALF_EVEN);

try this for your divide statement, (the scale is 8 for your precision). What you're doing right now is dividing two large decimals, which results in an ultra large decimal answer, and you're not controlling the precision.

Please note that the divide method has its own optional rounding mode parameter:

BigDecimal result=val1.divide(val2, BigDecimal.ROUND_UP);
