SqlFunctions.Atan2 Method

Definition

Namespace:

System.Data.Objects.SqlClient

Assembly:

System.Data.Entity.dll

Returns the positive angle, in radians, between the positive x-axis and the ray from the origin through the point (x, y), where x and y are the two specified numerical values. The first parameter passed to the function is the y-value and the second parameter is the x-value.

Overloads

Atan2(Nullable<Decimal>, Nullable<Decimal>)	Returns the positive angle, in radians, between the positive x-axis and the ray from the origin through the point (x, y), where x and y are the two specified numerical values. The first parameter passed to the function is the y-value and the second parameter is the x-value.
Atan2(Nullable<Double>, Nullable<Double>)	Returns the positive angle, in radians, between the positive x-axis and the ray from the origin through the point (x, y), where x and y are the two specified numerical values. The first parameter passed to the function is the y-value and the second parameter is the x-value.

Remarks

You cannot call this function directly. This function can only appear within a LINQ to Entities query.

This function is translated to a corresponding function in the database. For information about the corresponding SQL Server function, see ATN2 (Transact-SQL).
