What is the binary equivalent of the hexadecimal D plus 7?
D7 = 11010111
What is the hexadecimal for ABCDEF?
"The hexadecimal code of ABCDEF" is rather difficult to make. If you want the DECIMAL code for the HEXADECIMAL numbers A, B, C, D, E and F, then you get this explanation: Hexadecimal means 16 and if you are counting hexadecimal and you will start to count from 0 to 9 normally. Then you get A for 10, B for 11, C for 12 D for 13 E for 14 and F for 15.
What is the base of Hexadecimal number system and write its permissible symbols?
The base in a hexadecimal system is 16. The symbols are: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
What are the numbers used in the Hexadecimal number system?
The numbers used are 0, 1, 2, ... , 15. However, the numbers 10 to 15 are denoted by A, B, C, D, E and F. This is to distinguish between, for example, the decimal 11 and the hex 11. The latter is 1*161 + 1 (in decimal) or 17 (in decimal).
Write a program that prints a table of the binary, octal and hexadecimal equivalents of the decimal numbers in the range 1 through 256?
import java.util.Scanner; public class NumberSystem { public void displayConversion() { Scanner input = new Scanner(System.in); System.out.printf("%-20s%-20s%-20s%-20s\n", "Decimal", "Binary", "Octal", "Hexadecimal"); for ( int i = 1; i <= 256; i++ ) { String binary = Integer.toBinaryString(i); String octal = Integer.toOctalString(i); String hexadecimal = Integer.toHexString(i); System.out.format("%-20d%-20s%-20s%-20s\n", i, binary, octal, hexadecimal); } } // returns a string representation of the decimal number in binary public String toBinaryString( int dec ) { String binary = " "; while (dec >= 1 ) { int value = dec % 2; binary = value + binary; dec /= 2; } return binary; } //returns a string representation of the number in octal public String toOctalString( int dec ) { String octal = " "; while ( dec >= 1 ) { int value = dec % 8; octal = value + octal; dec /= 8; } return octal; } public String toHexString( int dec ) { String hexadecimal = " "; while ( dec >= 1 ) { int value = dec % 16; switch (value) { case 10: hexadecimal = "A" + hexadecimal; break; case 11: hexadecimal = "B" + hexadecimal; break; case 12: hexadecimal = "C" + hexadecimal; break; case 13: hexadecimal = "D" + hexadecimal; break; case 14: hexadecimal = "E" + hexadecimal; break; case 15: hexadecimal = "F" + hexadecimal; break; default: hexadecimal = value + hexadecimal; break; } dec /= 16; } return hexadecimal; } public static void main( String args[]) { NumberSystem apps = new NumberSystem(); apps.displayConversion(); } }
