7. Identify both the 8-bit mask and the Boolean operation needed to accomplish each of the following objectives: a. Round-off a given unsigned integer to the next closest odd number greater than or equal to the given number, e.g., 2 becomes 3, 5 remains 5. b. Convert any ASCII decimal digit into its corresponding numeric 8-bit value. Note: '0' =0011 0000, '1'- 0011 0001, 2 + 0011 0010, ... 19-0011 1001 8. Convert the decimal fraction-0.7215 to binary with minimum of 5 places to the right of the binary point. Show how you obtained each bit. 9. Give the single-precision IEEE 754 bit pattern for the following normalized binary value
