Floating point binary multiplication
WebExample • Let's suppose a multiplication of 2 floating-point numbers A and B, where A=-18.0 and B=9.5 • Binary representation of the operands: A = -10010.0 B = +1001.1 • Normalized representation of the operands: A = -1.001x24 B = +1.0011x23 • IEEE representation of the operands: A = 1 10000011 00100000000000000000000 B = 0 … WebThe multiplication of two floating point numbers is analogous to multiplication in scientific notation. For example, to multiply 1.8x times 9.5x : Perform unsigned integer multiplication of the mantissas. The decimal point in the sum is positioned so that the number of decimal places equals the sum of the number of decimal places in the numbers.
