[lmi-commits] [lmi] master 2f9e574 4/8: Add a failing unit test

[Greg Chicares]

branch: master
commit 2f9e57413c83bf1cd8616b2f005b254b5f8f44f8
Author: Gregory W. Chicares <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Add a failing unit test
    
    If rounded for printing, 999999.9 becomes 1000000, so it needs scaling
    if 1000000 does.
