Description

Suppose we have a requirement like below:

we want to get the rows with one specified column value larger than A and less than B.
(They are all decimals or integers)
namely:
A < Integer.valueof(column) < B

Use BinaryComparator will not help us to archive that goal:
e.g. suppose A = 100, B = 200, one column value is 110000.
So it can satisfy that condition, but it's not the row we wanted.

So I suggest to add one comparator to help implementing this.
