radians

1. RADIANS Function​

The RADIANS function in H2 database is used to convert an angle from degrees to radians.

2. Syntax​

The syntax for the RADIANS function in H2 database is as follows:

RADIANS(angle)

Arguments​

  • angle: The angle in degrees that needs to be converted to radians. It should be a numeric value.

Return​

  • The RADIANS function returns the angle converted to radians.

3. Notes​

  • The RADIANS function in H2 database expects the angle to be in degrees.
  • If the input angle is not a number or exceeds the numeric range, the RADIANS function will return NULL.
  • Ensure that you use the correct syntax and provide the angle in degrees while using the RADIANS function to avoid errors.

4. Examples​

Here are a few examples demonstrating the usage of the RADIANS function in H2 database:

Example 1 - Converting 45 degrees to radians:​

SELECT RADIANS(45) AS radians;

Output:

radians
------------------
0.7853981633974483

Example 2 - Converting angles stored in a column to radians:​

CREATE TABLE angles (
  id INT PRIMARY KEY,
  degree DOUBLE
);

INSERT INTO angles VALUES (1, 30), (2, 60), (3, 90);

SELECT id, degree, RADIANS(degree) AS radians
FROM angles;

Output:

id | degree |         radians
---+--------+------------------------
1  | 30     | 0.5235987755982988
2  | 60     | 1.0471975511965979
3  | 90     | 1.5707963267948966
