批处理仅显示小数点后的2个字符

标签： batch-file

有没有人知道如何只显示小数点后的2个字符。

实施例： 19.123948493114变成19.12

不能使用％变量：〜5％因为小数点前的数字有所改变所以有时它会是19次，所以它将是123451213.12345123

两者都需要只显示小数点后的2个字符

- =编辑= - 这是我当前的脚本。

问题？ 其中一个驱动器毫无理由似乎不想切断。

我的缩短脚本调试文件。我切断了C：驱动器的整个功能以及G：驱动器之后的所有功能，因为这是问题的驱动器，我不能发布超过30k字符xD

新答案

当我看到你编辑的帖子时，我正在开发一个能够正确舍入结果的答案。

如果您打算使用PowerShell，您也可以使用它。我发现这个Windows PowerShell Tip of the Week显示了如何格式化数字。

整个脚本最好用PowerShell完成，但我对该语言没有任何专业知识。所以我把这个混合脚本拼凑在了一起。甚至可能有更好的方法来做混合解决方案，但这是有效的。它比原始版本快得多，因为它将PowerShell调用的数量减少到每个驱动器一个。

@echo off
setlocal enableDelayedExpansion
cls
for /f "tokens=1*" %%A in ('fsutil fsinfo drives') do for %%C in (%%B) do (
  fsutil fsinfo statistics %%C |FINDSTR /I /C:"The FSUTIL utility requires a local NTFS volume." >nul || CALL:GetDriveInfo %%C
)
exit /b

:GetDriveInfo
set "free="
for /f "tokens=2 delims=:" %%A in ('fsutil volume diskfree %~1') do (
  if not defined free (set free=%%A) else (set total=%%A & goto :break)
)
:break
set "cmd=$used=%total%-%free%;$usedP=$used/%total%;$used=$used/1073741824;$freeP=%free%/%total%;$free=%free%/1073741824;$total=%total%/1073741824;"{0:N2}" -f $used;"{0:P1}" -f $usedP;"{0:N2}" -f $free;"{0:P1}" -f $freeP;"{0:N2}" -f $total"
set i=0
for /f "delims=" %%N in ('echo !cmd!^|powershell -Command -') do (
  set /a i+=1
  set n!i!=%%N
)
set "drive=%~1"
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，并且您的脚本每个驱动器调用两次，再加上一次。

我认为使用单个WMIC调用更简单，更好。此解决方案不限于NTFS驱动器。

编辑 - 我通过学习如何使用多个变量引用正确格式化整个字符串来简化powershell代码。我可以对之前基于FSUTIL的解决方案

做同样的事情

我仍然对PowerShell输出进行后处理，以删除PowerShell在％符号前插入的空间。

@echo off
setlocal enableDelayedExpansion
cls
set "printCmd=;"Used Space: {0:N2} ({1:P1}^)`nFree Space: {2:N2} ({3:P1}^)`nTotal Space: {4:N2}" -f $used,$usedP,$free,$freeP,$total"
for /f "skip=1 tokens=1-3 delims= " %%A in ('wmic logicalDisk get deviceId^, freeSpace^, size') do if "%%C" neq "" (
  set "defineVarsCmd=$used=%%C-%%B;$usedP=$used/%%C;$used=$used/1073741824;$freeP=%%B/%%C;$free=%%B/1073741824;$total=%%C/1073741824"
  echo Drive Information For %%A
  for /f "delims=" %%S in ('echo !defineVarsCmd!!printCmd!^|powershell -Command -') do (
    set "str=%%S"
    echo !str: %%=%%!
  )
  echo(
)

我确信知道PowerShell的人可以轻松地从上面删除批处理部分，并提供更短的纯PowerShell脚本。


原始答案

注意 - 此原始答案在第二个十进制数字后截断。它没有进行任何舍入

将数字分为2部分，整数和分数。将“00”附加到小数部分以确保其具有至少2位数。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2位数。

以下代码需要十进制数作为第一个也是唯一的参数。

@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%

棘手的部分是获得整数部分。我使用变量扩展搜索和替换来将REM命令注入SET语句。

如果num = 19.123，则set part1=%num:.=&rem %变为set part2=19&rem 123

将十进制数舍入为1/100精度的本地批处理方法

我喜欢使用FOR / F将数字解析为整数和小数部分。但是您的原始代码在舍入逻辑方面存在潜在问题。

我没有确切地确定您的一个驱动器号失败的原因，但是代码中存在类似1.09的问题。 SET / A将09解释为十六进制，并将抛出错误，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，您的方法也会出现问题，但在您的情况下这种情况永远不会发生。

我不认为这些问题中的任何一个都会导致您的特定故障，但我认为我会提供一个纯批处理方法，可以将任何十进制数可靠地舍入到1/100精度。

同样，脚本需要一个十进制数作为第一个也是唯一的参数。

@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。只要输入数小于200000000且请求的小数位数小于或等于9，它就应该始终有效。

@echo off
:roundDecimal  number  precision
setlocal enableDelayedExpansion
for /f "tokens=1,2 delims=." %%A in ("0%~1") do (
  set "part1=%%A"
  set "part2=1%%B0000000000"
)
set /a len=%~2+1
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%
