字符串末尾的正则表达式为数字? [英] Regex for number at the end of string?

问题描述

我想确定字符串是否以数字结尾(带/不带小数).如果结束，我要提取它.

I want to find out if a string ends with number (with/without decimal). If it ends, I want to extracts it.

"Test1" => 1
"Test"  => NOT FOUND
"Test123" => 123
"Test1.1" => 1.1

我错过了一些细节.
1.在数字之前，字符串还可以包含特殊字符
2.它是单行，而不是多行.

I have missed a few details.
1. Prior to number, string can contain special characters also
2. It is single line, not multiline.

推荐答案

尝试一下此模式，

\d+(\.\d+)?$
