StrictMath toRadians() Method in Java
• Last Updated : 11 Oct, 2018

The java.lang.StrictMath.toRadians() method of StrictMath class in Java is used to accept an angle measured in degrees as a parameter and returns its approximately equivalent angle measured in radians. So basically it converts degree to radians. This conversion is generally inexact.

Syntax:

`public static double toRadians(double deg)`

Parameters: This function accepts a single parameter deg which refers to an angle in degrees which is to be converted to its equivalent radians.

Return Values: This method returns the measurement of the angle passed as a parameter, in radians.

Examples:

```Input : 120
Output : 2.0943951023931953

Input : 0.00087104
Output : 1.5202515916571408E-5
```

Below programs illustrate the java.lang.StrictMath.toRadians() method in Java :
Program 1:

 `// Java Program to illustrate ``// StrictMath.toRadians() function `` ` `import` `java.io.*;``import` `java.lang.*;`` ` `class` `GFG {``    ``public` `static` `void` `main(String[] args)``    ``{`` ` `        ``double` `deg = ``108.478``;``        ``double` `rad = StrictMath.toRadians(deg);``        ``System.out.println(``"Value in radian of "` `+``                      ``deg + ``" degrees is "` `+ rad);``    ``}``}`
Output:
```Value in radian of 108.478 degrees is 1.8932982659784086
```

Program 2:

 `// Java Program to illustrate StrictMath.toRadians()``// function `` ` `import` `java.io.*;``import` `java.lang.*;`` ` `class` `GFG {``    ``public` `static` `void` `main(String[] args)``    ``{`` ` `        ``double` `deg = ``360.0``;``        ``double` `rad = StrictMath.toRadians(deg);``        ``System.out.println(``"Value in radian of "` `+``                      ``deg + ``" degrees is "` `+ rad);``    ``}``}`
Output:
```Value in radian of 360.0 degrees is 6.283185307179586
```
