atan()

Example

Provide the arctangent of various numerical values.

System.out.println(Math.atan(0.5));
System.out.println(Math.atan(-0.5));
System.out.println(Math.atan(5));
System.out.println(Math.atan(-5));
System.out.println(Math.atan(100));
System.out.println(Math.atan(-100));

Definition and Usage

The atan() function computes the arctangent of a number in radians.

Tip: The atan() function restricts angles to the range of -π/2 to π/2. For wider angle ranges, consider using the atan2() function.

Syntax

public static double atan(double number)
