# Java.math.BigInteger.floatValue() Method

## Description

The java.math.BigInteger.floatValue() converts this BigInteger to a float. This conversion is similar to the narrowing primitive conversion from double to float.

If this BigInteger has too great a magnitude to represent as a float, it will be converted to Float.NEGATIVE_INFINITY or Float.POSITIVE_INFINITY as appropriate. Even when the return value is finite, this conversion can lose information about the precision of the BigInteger value.

## Declaration

Following is the declaration for java.math.BigInteger.floatValue() method.

```public float floatValue()
```

## Specified by

floatValue in class Number.

NA

## Return Value

This method returns this BigInteger converted to a float.

NA

## Example

The following example shows the usage of math.BigInteger.floatValue() method.

```package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

public static void main(String[] args) {

// create 2 BigInteger objects
BigInteger bi1, bi2;

// create 2 Float objects
Float f1, f2;

// assign values to bi1, bi2
bi1 = new BigInteger("123");
bi2 = new BigInteger("-123");

// assign float values of bi1, bi2 to f1, f2
f1 = bi1.floatValue();
f2 = bi2.floatValue();

String str1 = "Float value of " + bi1 + " is " +f1;
String str2 = "Float value of " + bi2 + " is " +f2;

// print f1, f2 values
System.out.println( str1 );
System.out.println( str2 );
}
}
```

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

```Float value of 123 is 123.0
Float value of -123 is -123.0
```
