Java - Double floatValue() method
Description
The Java Double floatValue() method returns the float value of this Double object.
Declaration
Following is the declaration for java.lang.Double.floatValue() method
public float floatValue()
Parameters
NA
Return Value
This method returns the float value represented by this object.
Exception
NA
Example 1
The following example shows the usage of Double floatValue() method to get a float primitive value of given positive Double object. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.
package com.tutorialspoint; public class DoubleDemo { public static void main(String[] args) { Double d = new Double("15.30"); //return the float value System.out.println("Value = " + d.floatValue()); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = 15.3
Example 2
The following example shows the usage of Double floatValue() method to get a float primitive value of given negative Double object. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.
package com.tutorialspoint; public class DoubleDemo { public static void main(String[] args) { Double d = new Double("-15.30"); //return the float value System.out.println("Value = " + d.floatValue()); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = -15.3
Example 3
The following example shows the usage of Double floatValue() method to get a float primitive value of given negative Double object of zero value. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.
package com.tutorialspoint; public class DoubleDemo { public static void main(String[] args) { Double d = new Double("-0.0"); //return the float value System.out.println("Value = " + d.floatValue()); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = -0.0
Example 4
The following example shows the usage of Double floatValue() method to get a float primitive value of given positive Double object of zero value. We've initialized a Double object with a given positive float value. Then using floatValue() method, we're printing its value.
package com.tutorialspoint; public class DoubleDemo { public static void main(String[] args) { Double d = new Double("+0.0"); //return the float value System.out.println("Value = " + d.floatValue()); } }
Output
Let us compile and run the above program, this will produce the following result −
Value = 0.0
