The Java language allows platforms to use available floating-point hardware that can provide /extended floating-point support/ with exponents that contain more bits than the standard Java primitive type double (in the absence of the strictfp modifier). Consequently, these platforms can represent a superset of the values that can be represented by the standard floating-point types. Floating-point computations on such platforms can produce different results than would be obtained if the floating-point computations were restricted to the standard representations of float and double. According to the Java Language Specification (JLS), §15.4, "FP-strict Expressions":
