Syntax
ARC_COSINE(Argument)
Description
The ARC_COSINE SQL scalar function returns the arc cosine of a number, in radians.
The ARC_COSINE and COSINE functions are inverse operations.
The argument must be a number whose value is greater than or equal to -1 and less than or equal to 1.
The data type of the result is double-precision floating point.
If the argument can be null, the result can be null; if the argument is null, the result is the null value.
The result is in the range (0, &pi.).
Example
Assume the column ACOSINE is a decimal (10,9) column with a value of 0.070737202.
ARC_COSINE(ACOSINE)
Returns the approximate value 1.49.
