The ASIN function in H2 database is used to calculate the arcsine of a given value.

2. Syntax​

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

ASIN(value)

Arguments​

  • value: The value for which the arcsine needs to be calculated. It should be a numeric value within the range of -1 to 1.

Return​

  • The ASIN function returns the arcsine of the given value in radians.

3. Notes​

  • The ASIN function in H2 database returns the result in radians.
  • The input value must be between -1 and 1. If the value is outside this range, the ASIN function will return NULL.
  • Ensure that the datatype of the input value is compatible with the ASIN function to avoid errors.

4. Examples​

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

Example 1 - Calculating the arcsine of 0.5:​

SELECT ASIN(0.5) AS arcsine;

Output:

arcsine
-------
0.5235987755982989

Example 2 - Calculating the arcsine of values stored in a column:​

CREATE TABLE values (
  id INT PRIMARY KEY,
  val DOUBLE
);

INSERT INTO values VALUES (1, 0.25), (2, 0), (3, -0.8);

SELECT id, val, ASIN(val) AS arcsine
FROM values;

Output:

id |  val  |       arcsine
---+-------+-------------------
1  | 0.25  |  0.2526802551420796
2  | 0     |  0.0
3  | -0.8  | -0.9272952180016122
