Syntax

RADIANS(x)

Parameters

x Required. Specify an angle in degrees.

Return Value

Returns the angle measured in radians.

Example 1:

The example below shows the usage of RADIANS() function.

SELECT RADIANS(0);
Result: 0

SELECT RADIANS(30);
Result: 0.5235987755982988

SELECT RADIANS(60);
Result: 1.0471975511965976

SELECT RADIANS(90);
Result: 1.5707963267948966

SELECT RADIANS(180);
Result: 3.141592653589793

SELECT RADIANS(-90);
Result: -1.5707963267948966

SELECT RADIANS(-180);
Result: -3.141592653589793

Example 2:

Consider a database table called Sample with the following records:

Datax
Data 10
Data 230
Data 360
Data 490
Data 5180

The statement given below can be used to convert the records of column x (containing values expressed in degrees) into radians.

SELECT *, RADIANS(x) AS RADIANS_Value FROM Sample;

This will produce the result as shown below:
