Math

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.
