Is the study available for perusal somewhere? ?(e.g.
FJCC) ?I'd like
 to see their logic. 
I do not know. The study is mentioned in the 360 history book.
  32 bit was a terrible choice when your floating point
word was 8 bit
 exponent and 24 bit mantissa, normalized to a 4 bit boundary,
 however. 
I do not think anyone has much great to say about S/360 floating point.
Anyway, single precision floating point (32 bit) is relatively
useless, no matter what machine it is on.
