libextra already has BigInt, BigUint and BigRational but not an arbitrary precision decimal type similar to Java's BigDecimal or SQL's NUMERIC type.

I just ran into a place where I needed this, so since no one's touched it since bringing it up in September, I'm gonna take a crack at it. Commenting here just for the record and to let other precision-demanding people know that it's on it's way.

Is this still in the works? I'd be interested in trying it out (I'm using nightly anyway, since I also want to use serde)

@emabee, if you want to work on this, I'd say @mdcox's claim has expired.

I believe a few developers are active with the bigdecimal crate:
