Question
Using only MIPS integer instructions, write a function that will make x = (y < z) where x is an integer and y and z are positive floating-point numbers. The resulting value of x should be the integer 0 or 1. Your function only needs to handle positive normal float values correctly, not negative values, NaN, etc. (Hint: the weightings of bit positions are different for floats and integers, but bits have less significance as you move to lower positions in both integers and floats.)
