I want to divide two large integers,

a = 23546654
b = 24979799

and to get the result in double.

回答1:

Try

double x = ((double) a) / ((double) b)

which first converts your ints to doubles and then does the division. If you have BigIntegers (which your tag indicates) you may use BigInteger.doubleValue() to extract the double value.

回答2:

This are plain int rather than BigInteger.

All you need is

double ratio = (double) a / b;

回答3:

BigInteger class has a divide method.

BigInteger result = a.divide(b);
