Binary and hexadecimal numbers

you will not be required to add two hexadecimal numbers • You must, however, understand that if you have the hexadecimal number 0xff3a05 0x5aff 0xa5210 0xff3a04 ff3a06 0x5afe 5b00 0xa520f a5211 26 Binary and hexadecimal numbers Beyond the scope of this course • Now, you could create addition and multiplication tables for both

Binary and hexadecimal numbers

Binary and hexadecimal numbers Note • We will not be performing difficult addition or multiplication problems in binary –The computer does these calculations and conversions –They will be reduced to adding 1or multiplying by 10 16 Binary and hexadecimal numbers Verbosity • One weakness of binary numbers is that they are verbose:

Hexadecimal Addition • Divide the sum of two digits by the number base (16) The quotient becomes the carry value, and the remainder is the sum digit 36 28 28 6A 42 45 58 4B 78 6D 80 B5 1 1 21 / 16 = 1, rem 5 Important skill: Programmers frequently add and subtract the addresses of variables and instructions

CHAPTER V NUMBER SYSTEMS AND ARITHMETIC

-UNSIGNED ADDITION-UNSIGNED SUBTRACT -SIGNED ADDITION • Subtraction of signed numbers can best be done with 2’s complement • Performed by taking the 2’s complement of the subtrahend and then performing addition (including the sign bit) • Example: 0011 1011 - 0111 1010 0011 1011 1000 0110 1100 0001 + 0 0111 1100 Carries 59 - 122

L’addition - WordPresscom

1-L’addition 0 + 0 = 0 0 + 1 = 1 1 + 1 = 0 2- La soustraction 0 – 0 = 0 0 – 1 = 1 et on retient 1 1 – 1 = 1 3- La multiplication La multiplication binaire s’effectue selon le principe des multiplications décimal, on multiplie donc le multiplicande par chacun des bits du multiplicateur

The RYB, CMYK, RGB, HSV and Hexadecimal Color

• In addition to providing a good description of human color perception, the RGB model is the basis for displaying colors in television and computer screens • The RGB model is also used for recording colors in digital cameras, including still image and video cameras • The RGB model is an additive system
