function Test-PowerShellProcessIs32Bit {
    # Returns $true if the PowerShell process is 32-bit, $false otherwise
    # Works on Windows PowerShell v1.0 through the newest versions of PowerShell
    #
    # The function returns a boolean value indicating whether the current
    # PowerShell process is 32-bit or 64-bit. This function works on all versions
    # of PowerShell, including PowerShell 1.0, 2.0, 3.0, 4.0, 5.0, 5.1, 6.0,
    # 7.0, and 7.1. The function works on both Windows PowerShell and PowerShell
    # Core.
    #
    # Example:
    # $boolIs32Bit = Test-PowerShellProcessIs32Bit
    # if ($boolIs32Bit) {
    #     Write-Host "This PowerShell process is 32-bit"
    # } else {
    #     Write-Host "This PowerShell process is 64-bit"
    # }
    #
    # This example will output "This PowerShell process is 32-bit" if the
    # PowerShell process is 32-bit, and "This PowerShell process is 64-bit" if
    # the PowerShell process is 64-bit
