...strictfp forces floating points (and any floating-point operations) to adhere to the IEEE745 standard. With strictfp, you can predict how yoru floating points will behave regardless of the underlying platform the JVM is running on...
For the exam, however, you don't need to know anything about strictfp other than what its used for, that it can modify a class or a nonabstract method declaration, and that a variable can never be declared strictfp.
