4 decimal in the schema markup

I’m configuring Google Merchant Center with the source as “Web site crawling”.

In some products there’s an error on prices, for example: for a price of 9,60€ GMC get 96.000,00€.

I have investigated the code of the products and detect that in some cases it show 4 decimals in the schema markup and some 2, and when it show 4, GMC get the wrong price.

The one that show the 4 decimals in the product editor have the price with only two decimals.

In Woocommerce I have this configuration:

• Thousands separator “.”
• Decimal separator “,”
• number of decimal places “2”

Here some screenshots:
