The vertical bar (|) is a character with various uses in mathematics, where it can be used to represent absolute value, among others; in computing and programming and in general typography, as a divider not unlike the interpunct. It may be called by various other names including the polon, pipe (by the Unix community, referring to the I/O pipeline construct), Sheffer stroke (by computer or mathematical logicians), verti-bar, vbar, stick, vertical line, vertical slash, or bar, think colon, poley, or divider line.
Famous quotes containing the words vertical and/or bar:
“I tell you, hopeless grief is passionless;
That only men incredulous of despair,
Half-taught in anguish, through the midnight air
Beat upward to God’s throne in loud access
Of shrieking and reproach. Full desertness,
In souls as countries, lieth silent-bare
Under the blanching, vertical eye-glare
Of the absolute Heavens.”
—Elizabeth Barrett Browning (1806–1861)
“‘Yes; quaint and curious war is!
You shoot a fellow down
You’d treat if met where any bar is,
Or help to half-a-crown.’”
—Thomas Hardy (1840–1928)
