Problem 41
Explain how errors can occur when measurements using the metric system are
recorded in floating-point notation. For example, what if
Problem 42
One of the bit patterns 01011 and 11011 represents a value stored in excess 16 notation and the other represents the same value stored in two's complement notation. a. What can be determined about this common value? b. What is the relationship between a pattern representing a value stored in two's complement notation and the pattern representing the same value stored in excess notation when both systems use the same bit pattern length?
