How can I format money in RainMeter?

Question

I'm attempting to take a number like 5342.9 and would like to format it into USD. Ideally the outcome would be $5,342.90. My Measure is:

[MeasureUSDValue]
Measure=Plugin
Plugin=WebParser
URL=[MeasureBTC]
StringIndex=1

[MeterColumnValue]
Meter=String
MeasureName=MeasureUSDValue
NumOfDecimals=2
Text=$%1

NumOfDecimals appears to be a thing, but it doesn't seem to be working for me.

Answer 1

$ is special char of regex for end of string, use \$ for USD sign
