UnSigned Integers: can represent zero, positive and negative integers.

Unsigned Integers: can represent zero and positive integers.

IN SIGN-MAGNITUDE sign bit, the value of …representing positive integer and … representing negative integer

for negative integers, the absolute value of the integer is equal to "the magnitude of the complement (inverse) of the (n-1)-bit binary pattern

for negative integers, the absolute value of the integer is equal to "the magnitude of the complement of the (n-1)-bit binary pattern plus
one

There are two representations of zero

There is only one representation for the number zero

beyond the range

below the range

Overflow happens if the carry in equal the carry out

A Single-Precision floating-point number occupies

A Double-Precision floating-point number occupies

Double Precision: mantissa ===> 1 bit + 23 bits

IEEE single-precision uses a bias of =127

Actual exponent is found by subtracting the bias from the stored exponent
