如何在 Perl 中的两个数字之间创建一个随机数 [英] How can I create a random number between two numbers in Perl

问题描述

我已经在其他编程语言中看到了许多其他方法来做到这一点......虽然我还没有在 Perl 中找到一种......

I've seen many other ways to do this in other programming languages... Though I havent found one in Perl yet...

我想要完成的是设置两个数字:

What I want to accomplish is to set two numbers:

$minimum = 100;
$maximum = 4000;

然后在这两者之间创建一个随机整数.(完整的号码)($random_num)

Then to create a random integer between those two. (whole number) ($random_num)

我查看了这个网站:http://perlmeme.org/howtos/perlfunc/rand_function.html

这是一个很好的资源，虽然不完全是这样.

Which is a good resource, although does not do exactly that.

推荐答案

my $x = $minimum + int(rand($maximum - $minimum));

http://perldoc.perl.org/functions/rand.html

注意这个范围排除 $maximum 本身.添加 1 以使其包含在内.

Note this range excludes $maximum itself. Add 1 to make it inclusive.
