int256 range on geth command line

Question

When I do the following on the geth command line:

20000000000000000000-19999999999999999989

it returns 0

I'm guessing this is because of a 64 bit limit on ints.

Is there a way to get it to return 11?

Answer 1

 web3.toBigNumber("20000000000000000000").minus(web3.toBigNumber("19999999999999999989"))
