4. Show the value of all bits of a 12-bit register that hold the number equivalent to decimal 297 a. binary b. excess-3 c. binary-coded octal d. binary-coded hexadecimal e. binary-coded decimal 5. Represent the number (-29.03125) 10 as a normalized floating point binary number with 18 bits where the mantissa has 12 bits (including a sign bit) and the exponent has 6 bits (including a sign bit). Show the contents of mantissa and exponent registers, if signed magnitude representation is used. 6. A 18-bit floating point binary number has 12 bits (including a sign bit) for the mantissa 6 bits (including a sign bit) for the exponent. The mantissa is a normalized fraction. Numbers in the mantissa and exponent are in signed-magnitude representation. What are the largest and smallest positive quantities that can be represented, excluding zero? Give your answers in decimal
