This keyword is used to restrict the floating-point calculation in java and securing the same output while performing operations in the floating-point variable on every platform.


he calculation of floating points is platform-dependent. I.e it totally dependent on the platform configuration on which class file run (16/32/64 bit processors). To find the solution of these type issues we use strictfp keyword. It was initially launched in JDK 1.2 version following IEEE 754 standards of floating-point computations.




Important Points


➡ strictfp is a modifier.

➡ we can use strictfp keyword with classes, interfaces, and methods only.

➡ All the methods declared in the class/interface, and all nested types declared in the class, are implicitly strictfp When a class or an interface is declared with strictfp modifier

➡ We can use strictfp with abstract classes/interfaces. 

➡ strictfp cannot be used with abstract 

➡ Since methods of an interface are implicitly abstract, strictfp cannot be used with any method inside an interface.


  1. public class Main {
  2. public static void main(String[] args) {
  3. // Making Object of StrictFp
  4. StricfpExample stricfpexample = new StricfpExample();
  5. double sum = stricfpexample.sum(20e+10, 5e+08);
  6. System.out.println("Sum: " + sum);
  7. sum = stricfpexample.sum(20e+10, 5e+08);
  8. System.out.println("Sum: " + sum);
  9. }
  10. }
  11. public strictfp class StricfpExample {
  12. // Normal method
  13. public double sum(double num1, double num2) {
  14. return (num1 + num2);
  15. }
  16. // strictfp metheod
  17. public strictfp double sum(double num1, double num2, double num3) {
  18. return (num1 + num2 + num3);
  19. }
  20. }


Output:

Sum: 2.005E11

Sum: 2.055E11


Note :

The strictfp keyword cannot be applied on abstract methods, variables or constructors.
