Question

我有一个PowerShell脚本，我希望它总是返回2位小数的数字（I.E 1 = 1.00,1.1 = 1.10,1.11 = 1.11）我已经成功地为1和1.11做了，但我能想到一个不会占用1.1空间的解决方案。多数民众赞成在我得到的东西：

$Result = $shippingprice % 2
IF ($Result -ne 1 -and $Result -ne 0)
{
  $shippingpricestring = "$" + $shippingprice.ToString()
}
else {
  $shippingpricestring = "$" + ($shippingprice | % { '{0:0.00}' -f $_ })
}
$Result = $itemprice % 2
IF ($Result -ne 1 -and $Result -ne 0)
{
  $itempricestring = "$" + $itemprice.ToString()
}
else {
  $itempricestring = "$" + ($itemprice | % { '{0:0.00}' -f $_ })
}
IF ($Result -ne 1 -and $Result -ne 0)
{
  $taxstring = "$" + $tax.ToString()
}
else {
  $taxstring = "$" + ($tax | % { '{0:0.00}' -f $_ })
}

$Result = $finalrice % 2
IF ($Result -ne 1 -and $Result -ne 0)
{
  $finalricestring = "$" +$finalrice.ToString()
}
else {
  $finalricestring = "$" + ($finalrice | % { '{0:0.00}' -f $_ })
}

Answer 1

$ shippingpricestring =＆＃34; $＆＃34; + $ shippingprice.ToString（＆＃34;＃。##＆＃34;）

脚本专家参考：Hey Scripting Guy

$shippingprice = 17.1111
$ItemPrice = 4.1211
$tax = 94.919
$finalrice =10.3211

$Result = $shippingprice % 2
IF ($Result -ne 1 -and $Result -ne 0)
{
  $shippingpricestring = "$" + $shippingprice.ToString("#.##")
}
else {
  $shippingpricestring = "$" + ($shippingprice | % { '{0:0.00}' -f $_ })
}

Write-Output $shippingpricestring

IF ($Result -ne 1 -and $Result -ne 0)
{
  $itempricestring = "$" + $itemprice.ToString("#.##")
}
else {
 $itempricestring = "$" + ($itemprice | % { '{0:0.00}' -f $_ })
}

Write-Output $itempricestring

IF ($Result -ne 1 -and $Result -ne 0)
{
  $taxstring = "$" + $tax.ToString("#.##")
}
else {
  $taxstring = "$" + ($tax | % { '{0:0.00}' -f $_ })
}

Write-Output $taxstring

$Result = $finalrice % 2
IF ($Result -ne 1 -and $Result -ne 0)
{
  $finalricestring = "$" +$finalrice.ToString("#.##")
}
else {
  $finalricestring = "$" + ($finalrice | % { '{0:0.00}' -f $_ })
}
Write-Output $finalricestring

RESULT
$17.11
$4.12
$94.92
$10.32

***以上假设所有变量都有超过2个小数位。如果说$ tax = 9.9 $ taxstring将显示为9.9而不是9.90

Answer 2

如果要使用.ToString格式化数字，可以使用.ToString（格式）

实施例

$list = 1, 1.1, 1.111, 1.1111
$list | %{$_.ToString("0.00")}

输出

1.00
1.10
1.11
1.11
