vinculum 1. (math) The bar that is placed over repeating decimal fractions to indicate the portion of the patterns that repeats. The Latin noun vinculum refers to a small cord for binding the hands or feet; likewise, the verb vincire means "to bind". The symbol was once used in the same way that parentheses and brackets are now used to bind together a group of numbers or symbols. Originally the line was placed under the items to be grouped. What today might be written 7(3x + 4) the early users of the vinculum would write 3x + 4 7. Sometimes the horizontal fraction bar is called a vinculum as it binds the numerator and denominator into a single value.
The vinculum is introduced in the Star Trek Voyager episode "Infinite Regress" (series 5, episode 7). In the year 2375, the starship Voyager encounters a Borg debris field in the midst of which is a still-functioning vinculum – the processing device at the core of every Borg vessel which, as the Bog put it,"brings order to chaos". Tapping into Seven of Nine's cortical implant, it attempts to re-integrate her with the Collective, resulting in a severe case of multiple personality syndrome for Voyager's ex-drone eye-candy.
