SQLite acosh() Function

The SQLite acosh() function returns the inverse hyperbolic cosine of a specified number.

Syntax

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

acosh(number)

Parameters

number

Required. A number used to compute the inverse hyperbolic cosine. It must be a value to give greater than or equal to 1.

Return value

The SQLite acosh() function returns the inverse hyperbolic cosine of a specified number.

If the value of the parameter is less than 1, the acosh() function will return NULL.

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

Examples

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

SELECT
    acosh(1),
    acosh(2),
    acosh(2000);

   acosh(1) = 0.0
   acosh(2) = 1.31695789692482
acosh(2000) = 8.29404957760202
