How to get stats on currency field?

[Pranaya Behera]

Hi,
    I have a currency field type. How do I get StatsComponent to work 
with it ? Currently StatsComponent works with strings, numerics but not 
currency field.
Another question is how to copy only the value part from a currency 
field ? e.g. if my field name is "mrp" and the value is "62.00, USD", if 
the currency field cannot be used in the StatsComponent then how can I 
copy only 62.00 to another field ?
