The Number Procedure is the list of tips that gives intending to expressions composed in that selection program. One example is, if we want to Convey that We have now ten pet dogs, during the decimal variety process we would create “10 canine,” while in the binary procedure “1010 canines,” in the octal program “12 pet dogs,” and inside the hexadecimal technique “A canines.” Each one of these statements stand for ten dogs but in various range units.
