Basic and Crystal syntax.

Argument

Returns

Number value

Action

Tan returns a Number specifying the tangent of an angle given in radians. It takes a right-angle triangle, and returns the length of the side opposite the specified angle divided by the length of the side adjacent to the angle.

Examples

The following examples are applicable to both Basic and Crystal syntax:

Tan (1)

Returns 1.5574 (rounded to 4 decimals). This is the tangent of 1 radian.

Tan (45 * crPi / 180)

Returns 1. This is the tangent of 45 degrees. Before taking the tangent, the angle is converted to radians by multiplying by crPi / 180.

Comment

This function is designed to work like the Visual Basic function of the same name.
