I want to take an 8-bit binary string 111 (call it by variable name r and mask off bits 7 and 8 (set them to zero) How do I use it? Use C syntax 3. Write 31.12510 in binary converting it like we did in class (fixed, not floating point!) 4. What is 01110.01102 in decimal? 5. Consider the hex string 0x73F02000. If we interpret this as a 32-bit floating point number, what would it be in decimal
