Question

Following the bit-level floating-point coding rules, implement the function with
the following prototype:
/* Compute 0.5*f. If f is NaN, then return f. */
float_bits float_half(float_bits f);
For floating-point number f , this function computes 0.5 . f . If f is NaN, your
function should simply return f .
Test your function by evaluating it for all 232 values of argument f and comparing
the result to what would be obtained using your machine’s floating-point
operations.
