branch: master
commit ac8dde2426810064855ab7c72118488ec16d62f3
Author: Gregory W. Chicares <address@hidden>

    Keep integers integral
    
    As suggested in the last commit message, rewrote a few lines so that a
    double, once converted to int, is stored as such, and no unnecessary
    mixed-mode arithmetic is subsequently performed upon it.
