This document proposes to unify the random number engines subtract_with_carry_engine<> and subtract_with_carry_01_engine<>. These engines employ the identical transition algorithm as well as the identical generation algorithm. In our opinion, these engines’
separation was a historical accident based solely on the types (integer- versus real-valued) of the values each was designed to return.
