    Affects Versions: ODF 1.2 CD 07

             Fix For: ODF 1.3 CSD 01


In ODF 1.2 the <number:fraction> element has the attribute number:denominator-
value. If this attribute is not present, a denominator that is appropriate for
displaying the number is used. Clearly what is considered appropriate will be implementation dependent/defined. For example LibreOffice considers the appropriate denominator for of:=PI() to be 7 although a denominator of 113 would create a much closer approximation. From a user perspective if formatting a number as a fraction usually the size of the denominator is important even if the exact chosen denominator does not matter. Some implementations, for example Gnumeric, permit the user to determine a maximum number of digits to be used in the choice of the denominator. Currently Gnumeric stores that information in a foreign element: gnm:max-denominator-digits. In the interest of interoperability it would be desirable to include a similar attribute in the ODF1.3 standard.
