Decimal type documentation

[Poyeyo via Digitalmars-d-learn]

Hello, has anyone used this https://github.com/andersonpd/decimal 
implementation?

I'm learning D and want to know where to start for the decimal 
(or bigfloat) stuff.

The goal is to be able to read and write some data from a SQL DB 
with a decimal(10,2) field.
