Comp-3 to hold negative Zero

CICS Guy · Posted: Fri May 09, 2008 6:13 pm

FWIW, I noticed this a couple weeks back while researching in the PoOp for another topic question....
Under some circumstances, a zero with a minus sign (negative zero) is produced. For example, the multiplicand:
00 12 3D (-123)
times the multiplier:
0C (+0)
generates the product:
00 00 0D (-0)
because the product sign follows the algebraic rule of signs even when the value is zero. A negative zero, however, is equivalent to a positive zero in that they compare equal in a decimal comparison.

Hai everybody

Sorry for the Delay. I was out of my station. Thank You CICS Guy. I asked How to include - sign with zero. Anyway It is meaningless. But Onsite asked me to do that. Now they dont need that. But I am interested to know. So I asked your suggestion. When I asked your suggestion. I didnt see CICS Guy post. Thank you for all.
