Java Float - toHexString() Method
The java.lang.Float.toHexString() method returns a hexadecimal string representation of the float argument. Some examples are shown below:
| Floating-point Value | Hexadecimal String |
|---|---|
| 1.0 | 0x1.0p0 |
| -1.0 | -0x1.0p0 |
| 2.0 | 0x1.0p1 |
| 3.0 | 0x1.8p1 |
| 0.5 | 0x1.0p-1 |
| 0.25 | 0x1.0p-2 |
| Float.MAX_VALUE | 0x1.fffffep127 |
| Minimum Normal Value | 0x1.0p-126 |
| Maximum Subnormal Value | 0x0.fffffep-126 |
| Float.MIN_VALUE | 0x0.000002p-126 |
Syntax
public static String toHexString(float f)
Parameters
f |
Specify the float to be converted. |
Return Value
Returns a hex string representation of the argument.
Exception
NA.
Example:
In the example below, the java.lang.Float.toHexString() method returns a hexadecimal string representing the given float argument.
import java.lang.*;
public class MyClass {
public static void main(String[] args) {
//creating float values
float x = 5.2f;
float y = -5.2f;
//printing the hexadecimal string for x
System.out.print("Hexadecimal string for x is: " );
System.out.println(Float.toHexString(x));
//printing the hexadecimal string for y
System.out.print("Hexadecimal string for y is: " );
System.out.println(Float.toHexString(y));
}
}
The output of the above code will be:
Hexadecimal string for x is: 0x1.4cccccp2 Hexadecimal string for y is: -0x1.4cccccp2
