Java - Float floatToIntBits() method
Description
The Java Float floatToIntBits() method returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout.It includes the following important points −
- If the argument is positive infinity, the result is 0x7f800000.
- If the argument is negative infinity, the result is 0xff800000.
- If the argument is NaN, the result is 0x7fc00000.
Declaration
Following is the declaration for java.lang.Float.floatToIntBits() method
public static int floatToIntBits(float value)
Parameters
value − This is a floating-point number.
Return Value
This method returns the bits that represent the floating-point number.
Exception
NA
Example 1
The following example shows the usage of Float floatToIntBits() method to get a int bits format of the given positive float value. We've initialized a Float object with a given positive float value. Then using floatToIntBits() method, we're printing its value in int bit format.
package com.tutorialspoint; public class FloatDemo { public static void main(String[] args) { Float d = new Float("15.30"); //returns the bits that represent the floating-point number System.out.println("Value = " + Float.floatToIntBits(d)); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = 1098173645
Example 2
The following example shows the usage of Float floatToIntBits() method to get a int bits format of the given negative float value. We've initialized a Float object with a given positive float value. Then using floatToIntBits() method, we're printing its value in int bit format.
package com.tutorialspoint; public class FloatDemo { public static void main(String[] args) { Float d = new Float("-15.30"); //returns the bits that represent the floating-point number System.out.println("Value = " + Float.floatToIntBits(d)); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = -1049310003
Example 3
The following example shows the usage of Float floatToIntBits() method to get a int bits format of the given zero float value. We've initialized a Float object with a given positive float value. Then using floatToIntBits() method, we're printing its value in int bit format.
package com.tutorialspoint; public class FloatDemo { public static void main(String[] args) { Float d = new Float("0.0"); //returns the bits that represent the floating-point number System.out.println("Value = " + Float.floatToIntBits(d)); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = 0
Example 4
The following example shows the usage of Float floatToIntBits() method to get a int bits format of the given negative zero float value. We've initialized a Float object with a given positive float value. Then using floatToIntBits() method, we're printing its value in int bit format.
package com.tutorialspoint; public class FloatDemo { public static void main(String[] args) { Float d = new Float("-0.0"); //returns the bits that represent the floating-point number System.out.println("Value = " + Float.floatToIntBits(d)); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = -2147483648
