I'm wondering how one would sort a column of decimal or currency values numerically in show-listview?

A contrived example:

$decimalArray = 1.1, 2.2, 3.3, 10.0, 20.0, 30.0

$props = @{
        Title = "Decimal Sorting"
        InfoTitle = "Decimal Sorting"
        InfoDescription = "Decimal Sorting"
        PageSize = 100000
$decimalArray | Show-ListView @props -Property @{Label = "Decimals"; Expression={$_}},
    @{Label = "Currency"; Expression={"{0:c}" -f $_}},
    @{Label = "Number"; Expression={"{0:n0}" -f $_}}

In the example above:

  1. The first column is a decimal
  2. The second column is currency
  3. The third column is an integer

Only the integer sorts numerically. It seems as soon as a decimal or currency symbol is added to the value, ListView treats the data as a string.

Might I sort decimals and currency numerically?

Thank you, vic


Spe uses the class ListViewComparer to handle the sorting. It appears as of 6.1 it sorts DateTime, int, and finally string.

You can submit a feature request or a pull request if you would like to see more datatypes covered.

public int Compare(String str1, String str2)
    DateTime dateTime1, dateTime2;
    if (DateTime.TryParse(str1, out dateTime1) && DateTime.TryParse(str2, out dateTime2))
        return DateTime.Compare(dateTime1, dateTime2);

    int int1, int2;
    if (int.TryParse(str1, out int1) && int.TryParse(str2, out int2))
        if (int1 < int2)
            return -1;
        return int1 > int2 ? 1 : 0;

    return String.Compare(str1, str2, StringComparison.Ordinal);


This should be included in 6.2. See the GitHub issue for more details.
