Chapter 14 Working with Java

The strictfp keyword

Floating-point hardware may calculate with more precision and with a greater range of values than required by the Java specification. The strictfp keyword can be used with classes or operations in order to specify compliance with the Java specification (IEEE-754). If this keyword is not set, then floating-point calculations may vary between environments.

Steps To enable the strictfp keyword:

  1. Double-click a class to open its property sheet.
  2. Click the Extended Attributes tab, and then click the Java sub-tab.
  3. Find the strictfp entry in the Name column, and set the Value to "true".
  4. Click OK. The class will be generated with the strictfp keyword, and will perform operations in compliance with the Java floating-point specification
