Convert Decimal to Binary

Hi,

Is there a possibility with Windows Power Shell to convert from decimal to
binary?

Like the "decbin" Function in PHP.

Try:

# convert 192 to binary form
PS > [Convert]::ToString(192,2).PadLeft(8,"0")
11000000

function decbin([int]$num) {
$i = 0
$bin = ""
do {
$bin = "$($num % 2)$bin"
$num = [Math]::Truncate($num / 2)
if (++$i % 4 -eq 0) {$bin = " $bin"}
} while ($num -gt 0)
$bin
}

The one tricky part is using the Truncate method. You would think that you
could just use integer division within PowerShell but noooo. It uses
banker's algorithm rounding so odd nums round up and even's round down.
Considering that not many bankers will ever use PowerShell I have no idea
why they chose that form of rounding or rounding at all! It seems like to
me that integer division should just truncate like it does in C.

and the reverse conversion is done with:

ps> [convert]::toint32("10000", 2)
16

For padding with zeros, use:

ps> [convert]::tostring(16, 2).padleft(8, "0")
00010000

Admittedly ToString() is not the first place i'd look for this
either ;-)
