Lines: 13 Summary: > (discussion about machines where 0.0 does not have same representation as 0) The CDC Cyber series represents floating-point zero with the (12-bit) exponent zero. It doesn't matter whether the (48-bit) mantissa is zero or not. If you normalize such a number, though, I believe you get back a mantissa of zero. Integer zero is 60 bits of all zeros or all ones (1's-complement machine). /jeff -- security!jjg@mitre-bedford.ARPA (MIL) {allegra,ihnp4,utzoo,philabs,uw-beaver}!linus!security!jjg (UUCP)
