			== <span style="color: red;">Note</span> ==

			This script fails on 1.0 and 1.00 and I haven't had time to fix it (probably never will).
			Instead I very much recommend [[User:Instructor\|Instructor]]'s [[VersionCompare]] script, which works flawlessly.

== Tested Version Numbers ==
Current VersionCheck function will compare the following version strings successfully...

*"3.1.0" "3.10.0"
*"0.6" "6"
*"6.0" "6"
*"5.1.1.0" "5.1.1.0"
*"9.1" "9.1.9"
*"1.01" "1.10"
*"2.5.09" "2.5"
*"2.5.9" "2.5.01"
*"7" "10.0.0.3646"
*"1" "11"
*"91.1.1.1" "101.1.1.1"
*"1.001" "1.0"

== Usage ==
<highlight-nsis>
${VersionCheckNew} "version 1" "version 2" "$[output variable]"
</highlight-nsis>

== Example ==
<highlight-nsis>
${VersionCheckNew} "1.0.1" "1.1.0" "$R0"
MessageBox MB_OK "Return value: $R0" ;outputs 2
</highlight-nsis>

== Output values ==
{| border="1" cellpadding="5"

== Version History ==
*'''v5: 28 March 05'''
**Re-wrote code again after a lot of thinking :p. Was failing for 1 and 11 (would say 1 was bigger than 11!)
**Changed function name to VersionCheckV5
**Fixed small bug (thanks Instructor!)

*'''v4: 22 March 05'''
**Check per digit would fail on 10.0 and 7.0 (thanks <i>Daijoubu</i>; it would say 1st was smaller).<br />The code has now been replaced with a more advanced method.

*'''v3: 13 Feb 05'''
**Added check per digit per number.
**Changed function name back to VersionCheckNew.

*'''v2: 10 Jan 05'''
**Re-written whole function.
**Changed function name to VersionCheckNew2.

*'''v1: 9 Dec 04'''
**First version.
