As3 currently only provides the int, uint, and number numeric types. The valid value range of an int is-2 ^ 31 ~2 ^ 31-1 (-2147483648 ~ 2147483647). uint indicates the unsigned integer. The valid value range is0 ~ 2 ^ 32-1 (0 ~ 4294967295) in Adobe official instructions, the expression of number is: "number data types can represent integers, unsigned integers, and floatingPoints ." To improve performance as much as possible, the number data type shoul

result is0, 4Because the VaR keyword is used inside the function to maintain the scope of a within outfun. Let's look at the following code: JS CodeFunction outerfun (){// No VaRA = 0;Alert ();}VaR A = 4;Outerfun ();Alert ();Result:0, 0That's strange. Why? The scope chain is the term used to describe a path. The variable value can be determined along this path. when a = 0 is executed, because the VaR keyword is not used, the value assignment op

Today, let's look at two simple questions. Problem:The sum of values. Analysis:It is easy to see that the result of the continuous number is the same, that is, the cycle section length is. For, you need to first reduce the power, the formula used is as follows: The worst time compl

int type, which is specified in the C and C ++ standards. In some compilers, void main can be compiled (such as vc6), but not all compilers support voidMain, because the standard has never defined void main. In G ++ 3.2, if the return value of the main function is not of the int type, it cannot be compiled. Gcc3.2 issues a warning. Therefore, if you want your program to be highly portable, use int main. 4. Function of return value the return value of main function is used to indicate the exit s

.) Add10001.101Shift to the right until only one digit before the decimal point reaches the 4 power of 1.0001101x2 (because 4 digits are shifted to the right ). In this case, the base number m and the index e come out: The base number is M. Because it must be 1 before the decimal point, IEEE requires that only the decimal point be recorded. Therefore, the base number here is0001101. Exponential part E, which is actually 4, but must be added to 127, fixed to 131, that is, binary number10000011 S
