Suppose you compile and run the following micro-benchmark program in an attempt to see how quickly floating-point multiplications are computed. main() {        float f = 1.0;        for (int i=0; i<1000000; ++i) f = f * f; } That code ran very fast, so you change the loop termination condition from i<1000000 to i<1000000000 to make it take longer to run, and recompile the program. Oddly, the new version takes exactly the same amount of processor time to execute. What probably happened?

Question

Suppose you compile and run the following micro-benchmark program in an attempt to see how quickly floating-point multiplications are computed.

main() {

       float f = 1.0;

       for (int i=0; i<1000000; ++i) f = f * f;

}
That code ran very fast, so you change the loop termination condition from i<1000000 to i<1000000000 to make it take longer to run, and recompile the program. Oddly, the new version takes exactly the same amount of processor time to execute. What probably happened?
