Perhaps you are referring to the scalar class at
http://RussP.us/scalar.htm

The nice thing about this one (which I wrote myself) is that after you
do your development and are ready for "production" runs, you can easily
disable the unit checks and get the efficiency of built-in numeric
types. That can be two orders of magnitude faster!

It comes with a complete user manual too (pdf and html). I'm using it
for my engineering work, and it's working great!
