It won't for me as I don't ever work with values accurate to that many
decimal points. There's a solid argument for dropping any digits past your
*least* accurate data point. It's kind of absurd to see results of 83.739%
when the +- error is 3%. The .### is a bit misleading...makes it look more
accurate than it has any point of being.

So, in my case, no, it won't matter. I think that the manuals do a good job
of describing *and* explaining where data might come in/out a bit
differently. Nothing was mentioned about the # of decimals on a real, so I
thought I'd mention that I'd noticed something.
