I hope you like your coffee forthy Rod!

I agree, 2 13/64" is much more direct and also looks a lot more elegant
than 2.203125"! (Thanks, Windows Calculator!) Anyway, what good old tape
measure could accurately measure all those tiny numbers, eh? And if you
use one of those laser thingies, who's to say there wasn't a bit of
grime or dust in the way, affecting the reading?

Stating a measurement of 2 13/64" also allows for a reasonable margin of
flexibility anyway, say up to a quarter of a sixty-fourth of an inch
either way, but stating 2.203125" as a measurement automatically demands
an inherent accuracy of at least six decimal places - or, speaking in
fractions, plus or minus 1/1,000,000, or the figure will change up or
down by one least-significant digit, resulting in what people nowadays
think of as an error. Eek! Next thing, we'll be weighing bells in grams
and producing coffins that fit like lycra shellsuits!

Apologies for throwing in my 0.41666666666666667 new pence worth!
