This page, aside from being badly written, is misleading. As far as I can tell, what it is trying to describe is the floating-point format used by IBM's S/390 hardware, whose fp format dates back to the System/360 of the 1960s, and may also be similar to a 56-bit mantissa format used by some VAX machines. On the other hand, IBM POWER chips use the IEEE 754 format, and I can't find any reference to support the idea that the S/390 format is named the IBM Floating Point Standard. —Steven G.

Agreed. I have tidied it up a bit; the information down to the code section is useful and was basically correct, however. It should be renamed 'IBM Floating Point Architecture' .. is there an easy way to rename a Wikipedia page and all references to it? mfc 08:57, 20 Mar 2004 (UTC)
(Ah, rename is called 'move'. Done. mfc 08:15, 23 Mar 2004 (UTC))
The article by Gerwig et al. in the IBM Systems Journal 48(3) May/July 2004 refers to it as the "zSeries/trademark hexadecimal floating-point architecture (HFP)".

(Also, Wikipedia is not a code repository; the Java snippet is probably inappropriate, even if it is not a copyright infringement. Steven G. Johnson)

Agreed. Suggest commenting it out, or move it to here? mfc

One reason we still care about this format has been added. The code has been replaced with an algorithm, that I think could be valuable. --Tumb 22:01, 22 Mar 2004 (UTC)
