# BigDecimal scale() Method in Java

The java.math.BigDecimal.scale() is an inbuilt method in java that returns the scale of this BigDecimal.

• For zero or positive value, the scale is the number of digits to the right of the decimal point.
• For negative value, the unscaled value of the number is multiplied by ten to the power of the negation of the scale.

Syntax:

```public int scale()
```

Parameters: This method does not accepts any parameter.

Return value: This method returns the scale of this BigDecimal object.

Below program illustrates the working of the above mentioned method:

Program 1:

 `// Java program to demonstrate the ` `// scale() method ` ` `  `import` `java.math.*; ` ` `  `public` `class` `Gfg { ` ` `  `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` ` `  `        ``BigDecimal b1 = ``new` `BigDecimal(``"456.0"``); ` `        ``BigDecimal b2 = ``new` `BigDecimal(``"-1.456"``); ` ` `  `        ``// Assign the result of scale on ` `        ``// BigDecimal Objects b1, b2 to int objects i1, i2 ` `        ``int` `i1 = b1.scale(); ` `        ``int` `i2 = b2.scale(); ` ` `  `        ``// Print the values of i1, i2; ` `        ``System.out.println(``"The scale of "` `+ b1 + ``" is "` `+ i1); ` `        ``System.out.println(``"The scale of "` `+ b2 + ``" is "` `+ i2); ` `    ``} ` `} `

Output:

```The scale of 456.0 is 1
The scale of -1.456 is 3
```

Program 2:

 `// Java program to demonstrate the ` `// scale() method ` ` `  `import` `java.math.*; ` ` `  `public` `class` `Gfg { ` ` `  `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` ` `  `        ``BigDecimal b1 = ``new` `BigDecimal(``"745"``); ` `        ``BigDecimal b2 = ``new` `BigDecimal(``"-174"``); ` ` `  `        ``// Assign the result of scale on ` `        ``// BigDecimal Objects b1, b2 to int objects i1, i2 ` `        ``int` `i1 = b1.scale(); ` `        ``int` `i2 = b2.scale(); ` ` `  `        ``// Print the values of i1, i2; ` `        ``System.out.println(``"The scale of "` `+ b1 + ``" is "` `+ i1); ` `        ``System.out.println(``"The scale of "` `+ b2 + ``" is "` `+ i2); ` `    ``} ` `} `

Output:

```The scale of 745 is 0
The scale of -174 is 0
```
