Definition df-fzo 11095
Description: Define a function generating sets of integers using a half-open range. Read  ( M..^ N
) as the integers from 
M up to, but not including,  N; contrast with  ( M ... N ) df-fz 11004, which includes  N. Not including the endpoint simplifies a number of formulae related to cardinality and splitting; contrast fzosplit 11125 with fzsplit 11037, for instance. (Contributed by Stefan O'Rear, 14-Aug-2015.)
