In this article, we are going to cover the ATN2()function in which we will see how we can get the arc tangent of two given numbers. Let’s discuss one by one.
// here val1 and val2 are input. Input : ATN2(val1, val2) Output : Arc tangent result.
ATN2() :
It is the function that returns the arc tangent of two numbers.
Syntax :
ATN2(val1, val2)
Parameter :
This method accepts two-parameters as mentioned above and described below.
-
val1, val2:
It is the two numeric values to calculate the arc tangent.
Returns –
It returns the arc tangent of two numbers.
Example-1 :
When the arguments hold the positive number.
SELECT ATN2(2.53, 5.6);
Output :
0.42433793483800258
Example-2 :
When the arguments hold the negative number.
SELECT ATN2(-2.53, -5.6);
Output :
-2.7172547187517906
Example-3 :
When the PI() function passing one of the arguments.
SELECT ATN2(PI(), 4);
Output :
0.66577375002835382
