Java：将两个BigInteger对象划分为一个BigDecimal对象

Question

What is the easiest way, using the least amount of unnecessary overhead to divide two BigInteger objects and store it in a BigDecimal Object?

I have been trying to work around the problem and cannot find anything that does not use an extremely excessive amount of conversions.

Edit: Realized how stupid this question was, I'll leave it up for reference though

Answer 1

You can convert your BigIntegers into BigDecimals:

// bigIntX is a BigInteger
BigDecimal bigDecX = new BigDecimal(bigIntX);
BigDecimal bigDecY = new BigDecimal(bigIntY);

// to divide:
bigDecX.divide(bigDecY);

Answer 2

Convert both BigInteger to BigDecimal and then divide them.
