一个维度不是2的力量 one dimension is not a power of 2 一个维度不是2的力量
Today I needed a simple algorithm for checking if a number is a power of 2. The algorithm needs to be: Simple Correct for any ulong value. I came up with this simple algorithm: private bool IsPowerOfTwo(ulong number) { if (number == 0) return false; for (ulong power = 1;...

你是制作CS起源地图的纹理的吧？刚好我也刚刚遇见这个问题，你必须把图片的长和宽的像素调整为2的整数幂，也就是说图片长和宽像素必须为2的N次方，即图片的长和宽的像素只能是2,4,8,16,32,64,128,256,512,1024...以此类推，明白了吧？注意取消横纵比例的固定。

Please enter the base (b) and a exponent (n) to calculate bn: (b) to the power of (n) Calculate Answer: (0)2 = 0 to the power of 2 = 0 Explanation: (0) to the 2nd power or simply '0 to the 2nd' is obtained by multiplying 2 times the base 0 by itself. So, 02 = ...
