Bar (unit) Bar (unit) The bar is a metric unit of pressure, but is not approved as part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa, which is slightly less than the current average atmospheric pressure on Earth at sea level. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes, who was a founder of the modern practice of weather forecasting. The International Bureau of Weights and Measures (BIPM) lists the bar as one of the "non-SI units [that authors] should have the freedom to use", but has declined to
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.
