Have you looked at java.math.BigDecimal
I've never heard the unit "crores" before but it seems to be 10 million (10^7) right.Quote:

2^1010 is quite a big number. You can rewrite it as 2^(10*101) = (2^10)^101 = 1024^101. You can approximate this to 1000^101 which is (10^3)^101 = 10^(3*101) = 10^303.
This mean that 2^1010 approximately has 303 decimal digits. For such big integers you need BigInteger.
