Subject: | Re: [Caml-list] What library to use for arbitrary precision decimals |
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. -- Richard Jones, CTO Merjis Ltd.
