Float_abs - return bit-level equivalent of absolute value of f for * floating point argument f. * both the argument and result are passed as unsigned int's, but * they are to be interpreted as the bit-level representations of * single-precision floating point values. * when argument is nan, return argument.. * legal ops: any integer/unsigned operations incl. ||, & & . also if, while * max ops: 10 * rating: 2

i think the answer is a or d
