COT (Transact-SQL)

SQL Server 2005

傳回指定 float 運算式中指定角度之三角餘切函數 (Cotangent) (以弧度為單位) 的數學函數。

主題連結圖示 Transact-SQL 語法慣例

複製 

COT ( float_expression )

float_expression

這是一個 float 類型或能夠隱含地轉換成 float 之類型的運算式。

下列範例會傳回特定角度的 COT。

複製 
DECLARE @angle float
SET @angle = 124.1332
SELECT 'The COT of the angle is: ' + CONVERT(varchar,COT(@angle))
GO

以下為結果集： 

複製 
The COT of the angle is: -0.040312
