MSTD sets of integers and reals, and Freiman isomorphisms

An MSTD set is a finite set of number with more pairwise sums than differences. MSTD sets of integers have been studied extensively, but not MSTD sets of real numbers. A Freiman isomorphism theorem is used to transform MSTD sets of reals to MSTD sets of integers.
