...and wiggles decimal

Consider the following wiggle expression :

            5103105;104109

Telescoping from the left and right,

            5×10 = 50,

            50+3 = 53,

            53×10 = 530,

            530+5; = 535;

and

            9÷10=910 (= 0.9),

            910+4 = 4910    (= 0.9+4 = 4.9),

            4910 ÷10 = 49100 = 4.9÷10 = 0.49,


so that, adding, and using the decimal form of the fraction, we get

            5103105;104109 = 535.49.

The wiggle form on the left closely corresponds to the decimal form on the right.  The superdigits on the left are exactly the digits on the right.  The face value marker on the left corresponds to the decimal point on the right.  The interbases on the left are all explicitly 10.  The number on the right is implicitly in our usual decimal or base ten notation.
