Get Arcsine Method

The Get Arcsine method returns an approximate arcsine of the value that the number argument contains expressed in radians in the range of negative pi/2 through pi/2. If any of the following situations are true, then this method returns NaN:

• It cannot convert the value to a number.
• The value is greater than 1 or less than negative 1.

This method uses the same argument as the Get Absolute Value method. For more information, see Table 106.
