Be aware that if you have prices without a decimal separator (e.g. 124 instead of 124.0 or 124,0 i.e. stuff without a period or a comma, depending on region) the above won't work. Just saying...
But then, maybe the site always provides decimally separated prices, who knows?
ALSO: Please, please don't use update rates less than the default UpdateQuotes=600 which is once every ten minutes. If you do you could end up getting Webparser and all other Rainmeter users blocked from the site! I suspect this was what happened on the previous Bloomberg version when one ignoramus insisted on updating once every minute despite being repeatedly told the site only updated the prices every 2-3 minutes.
-- I've just been watching the Asian markets and prices from the Heng Seng and Shanghai exchanges are only updated every sixty-seventy (60-70) minutes.
Agreed, it seems much better to just capture the whole value and then manipulate decimals or whatever in a RegExp Substitute, instead of trying to directly get stuff formatted as you want to from the WebParser measure's RegExp.
