Question:
1 (a) Express the denary value 109 as (i) a binary number using an 8-bit byte; (ii) an octal number; (iii) a hexadecimal number. [6] (b) Numbers are held in floating point form with one byte for the mantissa (fraction) and one byte for the exponent (characteristic). All values are held in two's complement form and the mantissa is normalised. Using this format, write down the binary floating point values and the denary values of (i) the largest magnitude, positive number; (ii) the smallest magnitude, positive number; (iii) the largest magnitude, negative number; (iv) the smallest magnitude, negative number. (The denary values may be left as a product of a power of 2). [8] (c) Explain how accuracy can be improved in a floating point representation an...
