3a. Floating point struct Define a struct Single that describes the bit layout for a single precision floating point number. You should be able to compile this definition (using just the gcc -c step), but there is no code to run yet. You will need to use bit fields in the struct. Notice that you need to consider little endian vs. big endian. Your submission should answer the following questions about this program: Why does endian matter here and not for part 2? 3b. Printing floating point parts Define a method void printSingle(float f) that will print the parts of the floating point number as distinct values. A typical output should look like: For value 3.5, sign=0 exp =128, fraction=11000000000000000000000 To place the float into the struct, use a pointer cast or a union. For example, using a pointer cast to interpret the bits of a point number as an integer, you could say int i; *(float *)&i = f; To print a floating point number in printf, you typically use %f. Your submission should answer the following questions about this program: • Describe how pointer casting works to get the value into a different format. • Describe how you could break apart a floating point number into parts using bitwise operators? Would that care abo endian?
