VMS, that's even supported to some degree in the source tree, and OS/390 (aka z/OS); patches to support it have been rejected, but people will likely maintain a fork themselves. > The major non-IEEE floating-point formats that I know of, on big iron, > are the VAX, Cray and IBM formats; I believe anything else is too old > to worry about. Is this true? Mostly. For VAX, there exist two double formats: the D format, and the G format - not sure whether you counted them as two. > The IBM format is particularly > troublesome because it's base 16 instead of base 2 (so e.g. multiplying > a float by 2 can lose bits), but it appears that recent IBM machines do > both IBM format and IEEE format floating-point. I assume that the S-390 > buildbots are using the IEEE side---is this true? They run Linux, so yes. Notice that other people also run Python on z/OS.
