Subject: Re: [Caml-list] What library to use for arbitrary precision decimals
Date: Sun, 19 Feb 2006 16:38:39 +0000	[thread overview]

Before we go too far down the currency track (where I agree, using
integers is the way to go), my actual requirement is for a natural
OCaml mapping for the PostgreSQL NUMERIC/DECIMAL type:

http://www.postgresql.org/docs/current/interactive/datatype.html#DATATYPE-NUMERIC-DECIMAL

The database can define types like NUMERIC(6,4) which means 6 decimal
digits in total, 4 of them after the decimal point -- for example,
12.3456

There doesn't seem to me to be a good natural map for this type in the
stdlib.

Rich.

PS. You can find latest progress on PG'OCaml here:

http://merjis.com/tmp/pgocaml-0.3.tar.gz

I've already converted a few of our bigger programs to use this library.
