relatively small numbers with the binary system requires working with long strings of ones and zeroes. The hexadecimal (base 16) number system (often called "hex" for short) provides us with a shorthand method of working with binary numbers. One digit in hex corresponds to four binary digits (bits)‚ so the internal representation of one byte can be represented either by eight binary digits or two hexadecimal digits. Less commonly used is the octal (base 8) number system‚ where one digit in octal corresponds

4.3 4.3 Conversion Between Number Bases 169 Conversion Between Number Bases Although the numeration systems discussed in the opening section were all base ten‚ other bases have occurred historically. For example‚ the ancient Babylonians used 60 as their base. The Mayan Indians of Central America and Mexico used 20. In this section we consider bases other than ten‚ but we use the familiar HinduArabic symbols. We will consistently indicate bases other than ten with a spelled-out subscript

transfer. The chapter two also shows numbering systems used in computers. These are some importance skills that will help you in the computer field. Thirty plus years ago‚ the first personal computer terms such as bits‚ bytes‚ decimal‚ binary‚ and hexadecimal have come part of the common language‚ but these terms are not always used correctly. There are three numbering systems that computers use for the math and measurements. One of these systems is called decimal systems. Decimal numbers are normally

Number Systems‚ Base Conversions‚ and Computer Data Representation Decimal and Binary Numbers When we write decimal (base 10) numbers‚ we use a positional notation system. Each digit is multiplied by an appropriate power of 10 depending on its position in the number: For example: 843 = 8 x 102 + 4 x 101 + 3 x 100 = 8 x 100 + 4 x 10 + 3 x 1 = 800 + 40 + 3 For whole numbers‚ the rightmost digit position is the one’s position (100 = 1). The numeral in that position indicates how many ones
