Binary to Decimal

Convert these binary numbers to decimal. All five are in 2s-complement notation (can be positive or negative), but note that part (e) is fixed-point binary. For parts (a)-(d), enter the integer decimal value. For part (e), enter the full decimal value using as many digits after decimal as needed for the exact answer.

a. 0011 1001 0110 1110 =

b. 1011 0101 0010 1101 =

c. 0101 1110 1000 0111 =

d. 0110 0001 1101 1001 =

e. 0011 1001 . 1101 1000 (fixed-point binary) = (Enter exact answer, i.e., all non-zero digits before and after decimal)
