is there anyway to convert from Double to BigInteger?

Question

Is there anyway to convert from double value to BigInteger?

double doubleValue = 64654679846513164.2;
BigInteger bigInteger = (BigInteger) doubleValue;

I try to cast it but it didn't work.

Answer 1

You can convert the double into a BigDecimal and then into a BigInteger:

BigInteger k = BigDecimal.valueOf(doublevalue).toBigInteger();
