keyword strictfp

The strictfp keyword is used to force the precision of floating point calculations (float or double) in Java conform to IEEE’s 754 standard, explicitly. Without using strictfp keyword, the floating point precision depends on target platform’s hardware, i.e. CPU’s floating point processing capability. In other words, using strictfp ensures result of floating point computations is always same on all platforms.

The strictfp keyword can be applied for classes, interfaces and methods.


Rules

• strictfp cannot be applied for constructors.
• If an interface or class is declared with strictfp, then all methods and nested types within that interface or class are implicitly strictfp.
•  strictfp cannot be applied for interface methods.
