我似乎无法在任何地方找到答案，即使它是如此“基本”的事情，我会假设其他人已经做过。
无论如何，这里什么都没有。
我做了一个简单的批处理脚本作为计时器（计数） 它采用 dd:hh:mm:ss 格式，但只显示必要的内容。 例如，如果天数和小时数 = 0，则只有 mm:ss 等。
现在我从 0 到 9 时遇到了一个小问题...
我想让它说 00-01-02-03-04-05... 但现在它说 0-1-2-3-4-5.. .
假设我将时间放在一个循环中，延迟 1 秒总是增加一秒。
因为我正在使用数字，所以我创建了一个数字 /a 变量。但是如果小于 10，我似乎无法弄清楚如何在数字前添加 0...
到目前为止，我已经尝试了以下方法：
echo %s:""=0%
没关系，我在输入此内容时想出了解决方案...查看我的答案

这实际上比看起来要容易得多。
将任何简单（非 32 位溢出）数字转换为前导 0 的数字：
只需从前面带 1 的值中减去前面带 2 的值减去前面带 1 的值之间的差。
即 1[你的价值] - ( 2[你的价值] - 1 [你的价值] )
转换成前导0：
确定需要的前导 0 将数字设置为具有该数量的 0 加上它的当前值，然后选择最后 N 个字符，表示您希望拥有的总共 N 个数字。
即用 00 填充两位数，然后是当前值并选择最后两位数。
这里更容易演示使用我的时间函数和一些简单的函数来转换你喜欢的值：

【讨论】：
解决办法是这样的 -> set s=0%s%
然后只需转换回数值...通过set /a s+=0 Damn...
【讨论】：
set /a s=100%s% %% 100.
