Hexadecimal System
Hexadecimal System is commonly used in Computer Science because of the manner of addressing locations in the memory. Similarly to the Natural Binary Code it is a positional notation system with a radix of 16. The numbers are encoded using digits from “0” to “9” and letters from “A” to “F”, where “A” stands for “10”, “B” for “11” etc. As it is a positional notation system the same symbols are used for different orders of magnitude to represent numbers. A representation of a decimal number in hexadecimal system follows:
Example:
D809F3 = D*16^5+ 8 * 16^4+ 9* 16^2+ F * 16 + 3 * 16^0 = 13*16^5+ 8 * 16^4+ 9* 16^2+ 16 * 16 + 3 * 16^0 = 13631488+524288+2304+240+3 = 14158323
