Description	This unit contains all the mathematical routines. There are three routines that are part of the language, but are conceptually part of the Math unit. All routines in the Math unit except Math.Distance and Math.DistancePointLine are exported unqualified. (This means you can call the entry points directly.) Math.Distance and Math.DistancePointLine are exported qualified. All constants in the Math unit are exported qualified. (Both Math.PI and Math.E must be prefaced with "Math.".) Descriptions of all the subprograms in the Math module can be found in this chapter.
Constants	Math.PI   The constant p (3.14...). Math.E   The natural base e (2.718...).
Entry Points	abs*   The absolute value function. arccos   The arccos function (radians). arccosd   The arccos function (degrees). arcsin   The arcsin function (radians). arcsind   The arcsin function (degrees). arctan   The arctan function (radians). arctand   The arctan function (degrees). cos   The cosine function (radians). cosd   The cosine function (degrees). exp   The exponentiation function. ln   The natural logarithm function. max*   The maximum value function. min*   The minimum value function. sign   The sign function. sin   The sine function (radians). sind   The sine function (degrees). tan   The tangent function (radians). tand   The tangent function (degrees). sqrt   The square root function. Distance   The distance between two points. DistancePointLine   The distance between a point and a line segment. * Part of the language, conceptually part of the Math unit.
