Dear all:

There is a small bug in Google's Rich Snippet testing tool:

If the currency is "EUR", then the price may be rendered incorrectly - in some cases, the digits following the delimiter (99.xx - the fractional part) are treated as if they were part of the main digits (i.e. the integer part).

Example: 

foo:price a gr:UnitPriceSpecification ;
	gr:hasCurrency "EUR"^^xsd:string ;
	gr:hasCurrencyValue "99.00"^^xsd:float .

can, in some cases, show up as

EUR 9900.00

Google is working on the issue and we assume at this point that this is just a bug in the validator, not in the actual Google rendering component.

Other currencies are not affected, as far as we know.

As a work-around, we recommend that you remove the fractional part from currency values if it is ".00".

So for those values, please use

foo:price a gr:UnitPriceSpecification ;
	gr:hasCurrency "EUR"^^xsd:string ;
	gr:hasCurrencyValue "99.00"^^xsd:float .

or in RDFa

<div rel="gr:hasPriceSpecification">
<div typeof="gr:UnitPriceSpecification">
<div property="gr:hasCurrency" content="EUR" datatype="xsd:string"></div>
<div property="gr:hasCurrencyValue" content="99" datatype="xsd:float"></div>
</div>

instead of 

<div rel="gr:hasPriceSpecification">
<div typeof="gr:UnitPriceSpecification">
<div property="gr:hasCurrency" content="EUR" datatype="xsd:string"></div>
<div property="gr:hasCurrencyValue" content="99.00" datatype="xsd:float"></div>
</div>

This is just a precautionary measure. At this moment, we have not seen this bug in actual Google search results, just in the testing tool.


Best wishes
