As you can see the multiply function is much faster and the 0.000 figure just means the timing was so small it didn't register - maybe your PC just happened not to be doing anything else at the time so the code was still in RAM or somesuch.... This is a good example of why timing tests must be done over many repetitions and averaged. Since you are running near the limit of recordability you might increase the number of loop iterations to 1000...
