var int = require('int');
var large = int('1234567890').mul('1234567890');
console.log(large.toString());
//'1524157875019052100'
// other cool stuff
var add_me = int('123456').add('-123456');
var power_up = int(2).pow(10);

mod (value)
mod our int by {value} and return the new int
neg

cmp (value)
compare our value to {value}
return 0 if self and value are equal, -1 if self < value, 1 if self > value
lt (value)

lte (value)
return true if self <= value
