sign (redirected from zodiacal signs)

sign

In marketing and advertising, a device placed on or before a premises to identify its occupant and the nature of the business done there or, placed at a distance, to advertise a business or its products. The ancient Egyptians and Greeks used signs for advertising purposes, as did the Romans, who also, in effect, created signboards by whitewashing convenient sections of walls for suitable inscriptions. Early shop signs were developed when tradesmen, dealing with a largely illiterate public, devised certain easily recognizable emblems to represent their trades. Modern sign designers use various forms of animation and light.

A symbol that identifies a positive or negative number. In digital code, it is either a separate character or part of the byte. In ASCII, the sign is kept in a separate character typically transmitted in front of the number it represents
(+ and - is 2B and 2D in hex).

In EBCDIC, the minus sign can be stored as a separate byte (hex 60), or, more commonly, as half a byte (+ and - is C and D in hex), which is stored in the high-order bits of the least significant byte. For packed decimal, it is in the low-order bits of the least significant byte.
