Bar (unit) mb (rather than the proper mbar) to denote the millibar. Between 1793 and 1795, the word bar was used for a unit of weight in an early version of the metric system. Atmospheric air pressure is often given in millibars, where standard atmospheric pressure at sea level is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about . Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibars as the values are convenient. After the advent of SI units, some meteorologists began using hectopascals (symbol hPa) which are
Comparison of Object Pascal and C the ASCII character set codice_47 and codice_48 is a TAB character. In addition to codice_49 type, Object Pascal also has codice_50 to represent Unicode characters. In C, this is usually implemented as a macro or codice_16 with name codice_52, which is simply an alias for codice_24. In Pascal, boolean is an enumerated type. The possible values of boolean are false and true, with ordinal value of false=0 and true=1, other values are undefined. For conversion to integer, ord is used: There is no standard function for integer to boolean, however, the conversion is simple in practice: C has binary valued
