SQLite tan() Function

The SQLite tan() function returns the tangent of the specified radian.

Syntax

Here is the syntax of the SQLite tan() function:

tan(number)

Parameters

number

Required. A number used to calculate the tangent, in radians.

Return value

The SQLite tan() function returns the tangent of the specified radian.

If the parameter number is NULL, the tan() function will return NULL.

Examples

This example shows the basic usage of the SQLite tan() function:

SELECT
    tan(2.5),
    tan(0.2),
    tan(-0.5),
    tan(-0.2),
    tan(0),
    tan(pi());

 tan(2.5) = -0.74702229723866
 tan(0.2) = 0.202710035508673
tan(-0.5) = -0.54630248984379
tan(-0.2) = -0.202710035508673
   tan(0) = 0.0
tan(pi()) = -1.22464679914735e-16

Here, we use the pi() function to obtain an approximation of π.
