Pascal (unit) dB SPL, or 20 µPa. The airtightness of buildings is measured at 50 Pa. The units of atmospheric pressure commonly used in meteorology were formerly the bar, which was close to the average air pressure on Earth, and the millibar. Since the introduction of SI units, meteorologists generally measure pressures in hectopascals (hPa) unit, equal to 100 pascals or 1 millibar. Exceptions include Canada, which use kilopascals (kPa). In many other fields of science, the SI is preferred, which means Pa with a prefix (in multiples of 1000) is preferred. Many countries also use the millibars. In practically all other
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
