嗯很容易你不能......但是通过努力，你可以做任何事情！
搜索 > 450.20 的数字不是正则表达式的地方，而是：
h perl-patterns: Vim 没有实现（不幸的是）execution of arbitrary code in the regex: (?{perl code})。
这意味着您必须使用一些替换 (s) 或全局查找 (g) 将匹配项评估为一个数字，以便使用 VimL 轻松区分它。
但是您的问题要求/ 命令。所以让我们用正则表达式来做吧。思路是匹配：
- x > 1000：\d\d\d\d（即4位）
- x > 500: [5-9]\d\d
- x > 460: 4[6-9]\d
- x > 450: 45[0-9]
- 冒号后的更多内容
一个示例正则表达式可以占据一些位置。特别是因为我为每个模式重复了单词边界。
\%(\%([^0-9.]\zs\|^)[5-9]\d\d\%(.\d*)\?\%(\ze\D\| $)\|\%([^0-9.]\zs\|^)4[6-9]\d\%(.\d*)\?\%(\ze\D\|$)\ |\%([^0-9.]\zs\|^)45[1-9]\%(.\d*)\?\%(\ze\D\|$)\|\%([ ^0-9.]\zs\|^)\d*\d{4}\%(.\d*)\?\%(\ze\D\|$)\|\%([^0- 9.]\zs\|^)450.[3-9]\d*\|\%([^0-9.]\zs\|^)450.2[1-9]\d*\|\% ([^0-9.]\zs\|^)450.20\d*(\d\&[^0])\d*)
