The Equivalence Between Numbers and Leftins

     Z⁺ L_Z⁺
     Z ^- L_Z^-
     Z L_Z

Thus the integers can be considered a subset of the leftins. Z L.

     L_r Q.

The rational numbers have a 1-to-1 mapping with the rational leftins.

     I L_f .
     I L_f .

     C L_f .
     C L_f .

Some irrational and complex numbers are present in L_f but not all.
