Forums Scripts & Popups Automatically adding commas to big numbers?

I have a stats script that is always collecting data and returns large numbers every time. The numbers it returns appear as just numbers with no commas. So instead of the default '100000' (for example), is there a small snippet I could add that will automatically put a comma, starting from right to left, for every 3 digits? Example:

1000 - 1,000
10000 - 10,000
100000 - 100,000
1000000 - 1,000,000
etc.

Try this:

//echo -a $bytes(1000000.001,bd)

Retains decimal values, if supplied.

-genius_at_work

Try using the $bytes identifier with the b option.

//echo -a $bytes(1000000,b) <-- Like this
1,000,000 <-- Like this

Oh that's nice, real good. Thanks guys.

You would think such an identifier would have a better name than "$bytes"...

That's because the identifier is intended to be used for formatting a number of bytes into kilobytes, megabytes, etc. - the comma formatting is just a side-effect usage.
