commit 53de040b178cdf45d900016a0b9d58c4afbe40c2
Author: Gregory W. Chicares <gchicares@sbcglobal.net>

    Add an extra argument to currency(data_type)
    
    currency::data_type needn't necessarily be 'std::int64_t'; perhaps
    'double' would be better. Changing it to 'double' would ambiguate the
    currency(data_type) ctor:
        explicit currency(double    d)
        explicit currency(int       i)
    -   explicit currency(data_type i)
    +   explicit currency(data_type i, bool)
    Prevented that problem by adding an extra, disregarded argument.
