Question about Java Language Support for strictfp keyword usage.

[A Z]

-Do openEJB or TomEE have implementation for the strictfp keyword for floats and doubles to prevent underflow and overflow, and enforce arithmetic accuracy upon operator manipulations of those types? Certainly in 64 bit as well as 32 bit JVMs?

-Can someone tell me of a Java Virtual Machine that runs SE Java, at least version 5 or later, in 64 bit, on Windows, and has implemented the strictfp keyword so that it enforces that on float and double?

-Are there other JVMs that are 64 bit and have implemented strictp and run on the Mac? On Linux?

-What other strictfp JVMs are there?

Hi

Strictfp is part of java since years but unrelated to javaee. It doesnt
prevent underflow/overflow IIRC but guarantees arithmetic portability.
