本文介绍了批次仅显示小数点后2个字符的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
有人知道怎么只显示小数点后2个字符.
Does anyone know how to display only 2 characters past a decimal point.
示例: 19.123948493114变成19.12
Example: 19.123948493114 turns into 19.12
不能使用％variable:〜5％，因为小数点前的数字会发生变化，因此有时它会是19，而其他时候是123451213.12345123
Can't use %variable:~5% because the number before the decimal changes so sometimes it will be 19 other times it will be 123451213.12345123
两者都只需要在小数点后显示2个字符
Both need to only display 2 characters past the decimal point

问题? 毫无理由的其中一个驱动器似乎想不中断.
The Issue? one of the drives for no reason at all seems to want to not cut off.

我的缩短脚本调试文件.我切断了C:驱动器和G:驱动器之后的所有功能的全部功能，因为这是问题所在的驱动器，我不能发布超过30k个字符xD
My Shortened Script Debug File. I cut off the entire function for the C: drive and everything after the G: drive because that is the drive that is the problem, and i can't post more then 30k characters xD

新答案
我正在开发一个答案，以便在看到您编辑的帖子时正确舍入结果.
I was in the process of developing an answer that rounds the result properly when I saw your edited post.
如果要使用PowerShell，则最好也使用它.我发现了 Windows PowerShell每周技巧，其中显示了如何格式化一个数字.
If you are going to use PowerShell, you might as well really use it. I found this Windows PowerShell Tip of the Week that shows how to format a number.
整个脚本可能最好用PowerShell来完成，但是我对这种语言没有专门知识.所以我把这个混合脚本放在一起了.即使是混合解决方案，也可能有更好的方法，但这是可行的.它比原始速度快得多，因为它将每个驱动器的PowerShell调用数量减少到一个.
The whole script would probably best be done with PowerShell, but I don't have any expertise with that language. So I threw together this hybrid script. There is probably a better way to do even the hybrid solution, but this works. It is much faster than your original because it reduces the number of PowerShell calls to one per drive.

echo Drive Information For %drive:\=%
echo Used Space: %n1% (%n2: =%)
echo Free Space: %n3% (%n4: =%)
echo Total Space: %n5%
exit /b
我不喜欢使用FSUTIL，因为它需要管理员权限，它仅限于NTFS卷，并且您的脚本在每个驱动器上调用两次，外加一个时间.
I don't like using FSUTIL because it requires admin rights, it is restricted to NTFS volumes, and your script is calling it twice per drive, plus one additional time.
我认为使用单个WMIC调用会更简单，更好.此解决方案不仅限于NTFS驱动器.
I think it is simpler and better to use a single WMIC call instead. This solution is not restricted to NTFS drives.
Edit-我学习了如何正确格式化带有多个变量引用的整个字符串，从而简化了powershell代码.对于以前的基于FSUTIL的解决方案，我可以做同样的事情
我仍然对PowerShell输出进行后期处理，以删除PowerShell在％符号前插入的空间.
I still post-process the PowerShell output to remove the space that PowerShell inserts before the % sign.

我确定知道PowerShell的人可以轻松地从上面剥离批处理部分，并给出更短的纯PowerShell脚本.
I'm sure someone who knows PowerShell could easily strip out the batch portion from the above and give an even shorter pure PowerShell script.
原始答案
注意-此原始答案在第二个十进制数字后被截断.它不进行任何舍入
将数字分为2部分，即整数和小数. "00"表示会附加到小数部分，以确保它至少有2位数字.然后将数字重新组合在一起，在此过程中将小数部分截断为两位数.
Break up the number into 2 parts, the whole number and the fractional number. "00" is appended to the fractional portion to make sure it has at least 2 digits. Then put the number back together, truncating the fractional portion to 2 digits in the process.
以下代码将十进制数作为第一个也是唯一的参数.
The following code expects a decimal number as the first and only parameter.
@echo off
setlocal
set num=%1
set part1=%num:.=&rem %
set "part2=%num:*.=%"
if "%part2%" neq "%num%" (set "part2=%part2%00") else set "part2=00"
set "num=%part1%.%part2:~0,2%
echo num=%num%
棘手的部分是获取整数部分.我使用变量扩展搜索并替换为在SET语句中插入REM命令.
The tricky part is to get the whole number portion. I use variable expansion search and replace to inject a REM command into the SET statement.
如果num = 19.123，则set part1=%num:.=&rem %变为set part2=19&rem 123
If num =19.123, then set part1=%num:.=&rem % becomes set part2=19&rem 123
本机批处理方法将十进制数字舍入为1/100精度
我喜欢您使用FOR/F将数字解析为整数和小数部分.但是您的原始代码在四舍五入逻辑方面存在潜在的问题.
I like your use of FOR /F to parse the number into the whole and fractional portion. But your original code has potential problems with the rounding logic.
我还没有确切地诊断出您的一个驱动器号失败的原因，但是您的代码中有一个问题，例如1.09之类的值. SET/A会将09解释为十六进制，并且将抛出错误，因为9不是有效的十六进制数字.如果在.之前缺少整数部分，则您的方法也会出现问题，尽管这种情况永远不会发生.
I haven't diagnosed exactly why your one drive letter fails, but there is a problem in your code with a value like 1.09. SET /A will interpret 09 as hexadecimal and will throw an error because 9 is not a valid hex digit. Your method also has problems if the whole number portion is missing before the ., though that should never happen in your situation.
我认为这些问题都不是导致您特定故障的原因，但我想我将提供一种纯批处理方法，该方法应将任何十进制数字可靠地舍入为1/100精度.
I don't think either of those problems are causing your particular failure, but I thought I would provide a pure batch method that should reliably round any decimal number to 1/100 precision.
同样，脚本希望将十进制数作为第一个也是唯一的参数.
Again, the script expects a decimal number as the first and only parameter.
@echo off
setlocal
for /f "tokens=1,2 delims=." %%A in ("0%~1") do (
set "part1=%%A"
set "part2=1%%B000"
)
for /f "tokens=* delims=0" %%N in ("%part1%1") do (
set /a "part1=%%N/10, roundup=%part2:~3,1%/5, part2=%part2:~0,3%+roundup, part1+=(part2/200)"
)
set "num=%part1%.%part2:~1,2%"
echo num=%num%
最后，这是另一个版本，它将小数位数保留为第二个参数.只要输入数字小于200000000并且请求的小数位数小于或等于9，它就应该一直有效.
Finally, here is another version that takes the number of decimal digits to preserve as a 2nd parameter. It should always work as long as the input number is less than 200000000 and the requested number of decimal digits is less than or equal to 9.
@echo off
:roundDecimal number precision
setlocal enableDelayedExpansion
for /f "tokens=1,2 delims=." %%A in ("0%~1") do (

for /f "tokens=* delims=0" %%N in ("%part1%1") do (
set /a "part1=%%N/10, roundup=!part2:~%len%,1!/5, part2=!part2:~0,%len%!+roundup"
set /a "part1+=(!part2:~0,1!/2)"
)
if %~2 gtr 0 (set num=%part1%.!part2:~1,%~2!) else set num=%part1%
echo num=%num%
