# Java.math.BigDecimal.signum() Method

## Description

The java.math.BigDecimal.signum() returns the signum function of this BigDecimal.

## Declaration

Following is the declaration for java.math.BigDecimal.signum() method.

```public int signum()
```

NA

## Return Value

This method returns -1, 0, or 1 as the value of this BigDecimal is negative, zero, or positive.

NA

## Example

The following example shows the usage of math.BigDecimal.signum() method.

```package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

public static void main(String[] args) {

// create 3 BigDecimal objects
BigDecimal bg1, bg2, bg3;

// create 3 int objects
int i1, i2, i3;

bg1 = new BigDecimal("123");
bg2 = new BigDecimal("0");
bg3 = new BigDecimal("-12");

// assign the signum values of bg1,bg2,bg3 to i1,i2,i3 respectively
i1 = bg1.signum();
i2 = bg2.signum();
i3 = bg3.signum();

String str1 = "The Result of Signum function on " + bg1 + " is " + i1;
String str2 = "The Result of Signum function on " + bg2 + " is " + i2;
String str3 = "The Result of Signum function on " + bg3 + " is " + i3;

// print i1,i2,i3 values
System.out.println( str1 );
System.out.println( str2 );
System.out.println( str3 );
}
}
```

Let us compile and run the above program, this will produce the following result −

```The Result of Signum function on 123 is 1
The Result of Signum function on 0 is 0
The Result of Signum function on -12 is -1
```
