Aw - I think it's more elegant without the splitting and the +

It occurs to me that the initial two numbers are normally going to be
redundant. The number of digits between the 10 and either the end of the
number (if an integer) or the + will be the same as that denoted by the
number in front of the 10, except ...

OK - then the initial exponent is useful.

But if it's their everyday system they might cope with
5 10 1 2 3 4 5 6 7 8 9      :)

That I do find confusing   :)

Yep!

Why? I know our school rulers were regularly marked in either 8ths of
inches or 16ths or 32nds. But engineers regulars worked with 'thous',
plural of 'thou' /Taw/ = 1 thousandth of an inch; and British shoe sizes
are done by 'barleycorns', there being three barleycorns to an inch   :)

But what about the super-units of 'inch'? I suppose, on the analogy of
'second' above, we would have:
(1) inch = inch
2 inch   = foot (12 inches)
3 inch   = yard (3 feet)
4 inch   = rod _or_ pole_ (5.5 yards)
5 inch   = chain (4 poles)
6 inch   = furlong (10 chains)
7 inch   = mile (8 furlongs)

Asbestos suits were useful  ;)
