ASIN (Transact-SQL)
SQL Server 2008
Returns the angle, in radians, whose sine is the specified float expression. This is also called arcsine.
The following example takes a float expression and returns the ASIN of the specified angle.
/* The first value will be -1.01. This fails because the value is outside the range.*/ DECLARE @angle float SET @angle = -1.01 SELECT 'The ASIN of the angle is: ' + CONVERT(varchar, ASIN(@angle)) GO -- The next value is -1.00. DECLARE @angle float SET @angle = -1.00 SELECT 'The ASIN of the angle is: ' + CONVERT(varchar, ASIN(@angle)) GO -- The next value is 0.1472738. DECLARE @angle float SET @angle = 0.1472738 SELECT 'The ASIN of the angle is: ' + CONVERT(varchar, ASIN(@angle)) GO
Here is the result set.
