# StrictMath toRadians() Method in Java

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
```
