strictfp

strictfp modifier is used for floating-point calculations. This modifier makes floating point variable more consistent across multiple platforms and ensure all the floating point calculations are done according to IEEE 754 standards to avoid errors of calculation (round-off errors), overflows and underflows on both 32bit and 64bit architecture. This cannot be applied on abstract methods, variables or constructors.

// strictfp keyword can be applied on methods, classes and interfaces.

strictfp class A{}

strictfp interface M{}

class A{  
    strictfp void m(){}
}
