Decimal builtin?

I am curious what people use to represent decimals when with
no rounding
error? I have a need for this and have come up against a
brick wall. I was
hoping for something that was similar to BigDecimal in Java -
does Ruby have
anything like this?

Many thanks in advance for any replies received.

what is http://www.rubycentral.com/book/ref_c_bignum.html
or http://raa.ruby-lang.org/list.rhtml?name=bigfloat, no?

Thanks for your reply Botp, but wouldn’t this still be susceptible to rounding
error?
