Error in vb_number_format function?

[Linhnt]

I have writen my own modification in vbulletin 4.1.3 and It's have an error


My Language setting:
Decimal Separator: .
Thousands Separator: ,

Example error:

My number:

PHP Code:

$mynumber = 50000; 


if I use vb_number_format() in plugin:

PHP Code:

$formated = vb_number_format($mynumber); 


The result is corect: 50.000

But if I use number format in template:

{vb:number {vb:raw mynumber}}

The result is incorect: 50,000

What is the problem? Is It a bug of vbulletin??

Sorry, I can't post new issua in tracker.vbulletin.com
