I'd like to say thanks to all those who mailed and posted information. Here's
a summary of what I got:

The IEEE 854 standard is a radix and word-size independent version of IEEE 754.
Available from IEEE/CS and ANSI (and possibly, in the UK, from BSI).

The full title is `Radix Independant Floating Point Standard') and it is a
subset of 754 that omits details of the format and radix of the floating point
numbers, leaving things like accuracy requirements, exception handling,
not-a-numbers, and so on. It is almost the same as IEEE 754 but has somthing
like an extra definition at the start along the lines of "let b be the base
used" and a global replacement of b for 2 in the rest of the text.

Thanks again for those who posted this info.
