[comp.protocols.iso.dev-environ] ASN.1 REAL encodings

guse@CCC.NERSC.GOV (08/15/90)

I am confused about the REAL encoding used in ISODE.  It appears that the BER 
specifies that the mantissa of the real (in binary) is encoded as an unsigned 
integer.  (10.5.5 -- ISO8825)  However, pg. 299 of The Open Book, and 
apparently the ISODE implementation encodes the mantissa as a twos-complement 
integer.  I am interested in clarification/explanation of this inconsistency.
