6.4 Precision of Amounts (informative)
While this standard does not prescribe a specific precision for numeric values and amounts in particular, Music Licensing Companies usually use at least seven decimal places for specifying amounts to avoid rounding issues.
Some Music Licensing Companies, in particular when reporting revenues for private copy levies on a per track basis that are derived from the market share of a single track, require even more precision. Thus, some Music Licensing Companies use up to 14 decimal digits.
It is therefore recommended that Message Sender and Message Recipient can deal with at least seven decimal digits.
