Millionaire

A millionaire was an individual who possessed wealth of in currency in excess of one million dollars.

Following the mutation of Gary Mitchell, in 2265, following the USS Enterprise (NCC-1701)'s encounter with the galactic barrier, Hikaru Sulu presented the mathematics of the situation with regards to how Mitchell's abilities were increasing geometrically. He likened the situation to the analogy, stating, "that is, like having a penny, doubling it every day. In a month, you'll be a millionaire."
