WebTo make it clear floor rounds towards negative infinity,while integer division rounds towards zero (truncates) For positive values they are the same. int integerDivisionResultPositive= 125/100;//= 1 double flooringResultPositive= floor (125.0/100.0);//=1.0. For negative value this is different. WebJul 17, 2010 · int floor_log2_simple(unsigned long long n) { int c = 0; while (n) { n >>= 1; c++; } return c - 1; } These same algorithms implemented in Rust performed nearly identically. The top approach performed a tiny amount better - but by only by a couple nano seconds on average. No amount of tweaking the algorithm gave any better performance.
