Pow cmath c++

WebThe pow () function calculates the value of 2 raised to the value generated by ceil function. It rounds up n to the next power of 2. Similarly, the previous power of 2 less than n is calculated by 2 raised to the floor of the base-2 logarithm of n. The floor function rounds down to the nearest integer. WebNote that pow is a function that works with floating point numbers. Optimizations might lead to rounding errors or truncation during implicit coversion to int. Replace pow(i, 2) with i*i and you'll get pure integer arithmetic and thus exact results.
