Bar (unit) (symbol: cbar), and millibar (symbol: mbar or mb). The notation bar(g), though deprecated by various bodies, represents gauge pressure, i.e., pressure in bars above ambient or atmospheric pressure. The bar is defined using the SI derived unit, pascal: ≡ 100,000 Pa ≡ 100,000 N/m. Thus, is equal to: and 1 bar is approximately equal to: Notes: The word "bar" has its origin in the Greek word (), meaning weight. The unit's official symbol is bar; the earlier symbol b is now deprecated and conflicts with the use of b denoting the unit barn, but it is still encountered, especially as
Comparison of Pascal and C in modern Pascal as well). Example; Pascal: Status := Status + [StickyFlag]; Status := Status - [StickyFlag]; if (StickyFlag in Status) then ... or Pascal: Status := Status or StickyFlag; Status := Status and not StickyFlag; if StickyFlag and Status = StickyFlag then ... C: Status |= StickyFlag; Status &= ~StickyFlag; if (Status & StickyFlag) { ... Although bit operations on integers and operations on sets can be considered similar if the sets are implemented using bits, there is no direct parallel between their uses unless a non-standard conversion between integers and sets is possible. During expression evaluation, and in
