Ambient pressure concept of pressure becomes irrelevant, and it is undefined at a gravitational singularity. The SI unit of pressure is the pascal (Pa), which is a very small unit relative to atmospheric pressure on Earth, so kilopascals (kPa) are more commonly used in this context. The ambient atmospheric pressure at sea level is not constant: it varies with the weather, but averages around 100 kPa. In fields such as meteorology and underwater diving, it is common to see ambient pressure expressed in bar or millibar. One bar is 100 kPa or approximately ambient pressure at sea level. Ambient pressure may in
Vector Pascal Vector Pascal Vector Pascal is an open source compiler that extends the Pascal programming language. It is designed to support efficient expression of algorithms using the SIMD model of computation. It imports into Pascal abstraction mechanisms derived from Iverson's APL programming language. In particular it extends all operators to work on vectors of data. The type system is also extended to handle pixels and dimensional analysis. The compiler is implemented in Java. The syntax generally follows that of Turbo Pascal and includes all features of the ISO standard (ISO 7185-1990) except where overridden by Turbo Pascal. Features of Extended Pascal
