SQL Server 2000

Returns radians when a numeric expression, in degrees, is entered.

##### Arguments

numeric_expression

Is an expression of the exact numeric or approximate numeric data type category, except for the bit data type.

##### Return Types

Returns the same type as numeric_expression.

##### Examples
###### A. Use RADIANS to show 0.0

This example returns a result of 0.0 because the numeric expression to convert to radians is too small for the RADIANS function.

``````SELECT RADIANS(1e-307)
GO
``````

Here is the result set:

``````-------------------
0.0
(1 row(s) affected)
``````

This example takes a float expression and returns the RADIANS of the given angle.

``````-- First value is -45.01.
DECLARE @angle float
SET @angle = -45.01
SELECT 'The RADIANS of the angle is: ' +
GO
-- Next value is -181.01.
DECLARE @angle float
SET @angle = -181.01
SELECT 'The RADIANS of the angle is: ' +
GO
-- Next value is 0.00.
DECLARE @angle float
SET @angle = 0.00
SELECT 'The RADIANS of the angle is: ' +
GO
-- Next value is 0.1472738.
DECLARE @angle float
SET @angle = 0.1472738
SELECT 'The RADIANS of the angle is: ' +
GO
-- Last value is 197.1099392.
DECLARE @angle float
SET @angle = 197.1099392
SELECT 'The RADIANS of the angle is: ' +
GO
``````

Here is the result set:
