Describe step by step how to subtract 01001100 0011 from 01001010 0010. Have to leave the answer normalised.
Back (Answer)
First convert the two values to floating point numbers. 0100.1100 010.01010 Then convert the second value to a positive number as it is negative. (KEEP, FLIP AND ADD 1) 101.10110 Then add the two values together padding the ‘negative’ number with 1s. 0100.11000 1101.10110 ========== 10010.01110 Finally convert back to normalised form. Make sure to state in the given bits.
