Tan function

Syntax

Tan(angle)

Description

Use the Tan function to calculate the tangent of the given angle (opposite / adjacent).

Parameters

Parameter	Description
angle	A value in radians.

Note:

In theory, values of angle such that angle mod pi = pi/2 are not valid for this function, because inputs approaching such values produce results that tend toward infinity. In practice, however, no computer system can represent such values exactly. Thus, for example, the statement Tan(Radians(90)) produces a number close to the largest value PeopleCode can represent, rather than an error.

Returns

A real number.

Example

The following example returns the tangent of an angle measuring 1.2 radians:

&MY_RESULT = Tan(1.2);
