vb随机数和正弦值代码

Randomize'随机种子初始化DimInt_AAsIntegerInt_A=Int(Rnd()*10)'生成0-9之间的随机整数Int_A=Int(Rnd()*100)‘生成0-99之间的随机整数

为了生成某个范围内的随机整数,可使用以下公式：Int((upperbound-lowerbound+1)*Rnd+lowerbound)这里,upperbound是随机数范围的上限,而lowerbou

既然后边都会用abs了,为何前边不用.iy(0)相当于i-y(0)0iy(0)+-1相当于i-y(0)+-1如果i和y(0)都是integer,那么可以这样写abs(i-y(0))>1以此类推j,k

简单就是不会再问：....再答：不是不会是好久没做了差不多都忘了呵呵

Atn(X/Sqr(-X*X+1))这里的x是正弦值.

答：因为：1度=3.1415926……/180所以：sin(30)在编程时因写为：PrintSin(3.14159/180*30)这还不简单：dimxx=Sin(3.14159/180*30)prin
