commit e0300d3a623fe21224c22fc4f2c44565111c2ec9
Author: John Ralls <jralls at ceridwen.us>

    Replace the gnc:numeric pair with normal Scheme rationals.
    
    This allows direct conversion between Scheme numbers and gnc_numeric
    without the performance or accuracy penalties arising from using doubles
    as an intermediary.
