IntegerIntegers are numbers that do not have fractional parts, such as 42 and -23 . Integers can be 有符号 (positive, negative, 0) or 无符号 (positive, 0).Swift provides 8,16,32 and 64-bit signed and unsigned integer types. These integer types are similar

Let's take a look at the graph, which is a map of the values of the V8 engine version 4.7 and 4.9 math.random () functions, as I can understand. From that, maybe you think it's a QR code? In fact, this picture tells us one truth, the second graph

There are many functions have mask, representing the mask, if a bit mask is 0, then the corresponding src of the one does not calculate, mask to and matrix/roi/size equalMost functions support ROI, and if the image ROI is set, then only the ROI
