## BigDecimal Class precision() method

• precision() method is available in java.math package.
• precision() method is used to get the precision of this BigDecimal object and we all know the term precision is the number of digits represented in the un-scaled value.
• precision() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• precision() method does not throw an exception at the time of returning precision.

Syntax:

```    public int precision();
```

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of this method is int, it returns the precision of this BigDecimal object.

Example:

```// Java program to demonstrate the example
// of int precision() method of BigDecimal

import java.math.*;

public class PrecisionOfBD {
public static void main(String args[]) {
// Initialize two variables and
// first is of "short" and second is
// of "String" type
short val1 = 1321;
String val2 = "100.24";

// Initialize two BigDecimal objects
BigDecimal b_dec1 = new BigDecimal(val1);
BigDecimal b_dec2 = new BigDecimal(val2);

// By using precision() method - is to
// return the precision of this BigDecimal
// b_dec1 and precision is the number of
// digits in unscaled value i.e. 1321 so
// it returns 4 because total number of
// digits in this BigDecimal (1321) is 4
int precision = b_dec1.precision();
System.out.println("b_dec1.precision(): " + precision);

// By using precision() method - is to
// return the precision of this BigDecimal
// b_dec2 and precision is the number of
// digits in unscaled value i.e. 100.24 so
// it returns 5 because total number of
// digits in this BigDecimal (100.24) is 5
precision = b_dec2.precision();
System.out.println("b_dec2.precision(): " + precision);
}
}
```

Output

```b_dec1.precision(): 4
b_dec2.precision(): 5
```
