Usage of Rnd function in VB

Rnd is a function that can generate double-precision random numbers between [0,1). int(N) is a function that takes the largest integer less than or equal to N, such as int(4.5)=4, int(-4.5)=5.

int(rnd usage method:

int(rnd * 范围 + 基数）

For example: int(rnd*m n) means to generate a random number between [n,m n-1]

Example: Suppose you want to store 6 randomly generated integers between 40 and 60 (including 40 and 60) into a one-dimensional array suijishu(). The statement is:

dim suijishu(1 to 6) as integer, i as integer
for i = 1 to 6
suijishu(i)=int(rnd*21+40)
next i
