Hi Ken, > I was anticipating format-number(price,'####0.00') to always produce > a string of 8 characters in length, yet both processors I have (XT > and Saxon) are Java based and are using the Java library which is > known to have other problems for this function. I thought that, since the format-number() function is specifically based on Java's DecimalFormat class, that using the Java library would be *more* reliable than copying the functionality in another language? > Any alternative interpretations out there for the specification > wording of: "digit specifies the character used for a digit in the > format pattern; the default value is the number sign character (#)"? > Would anyone else expect the "#" to produce a space if no digit is > there? If that isn't the behaviour, then what is the utility of the > "#"? In the format pattern, the # stands for an optional digit and the 0 stands for a required digit. So: format-number(12345, '#,##0.00') => '12,345.00' format-number(1.5, '#,##0.00') => '1.50' format-number(0.543, '#,##0.00') => '0.54' format-number(12345, '#,###.##') => '12,345' format-number(1.5, '#,###.##') => '1.5' format-number(0.543, '#,###.##') => '.54' You need to have #s as well as 0s to allow you to specify the grouping size in numbers without getting leading 0s all over the place, and to specify the maximum number of decimal digits without forcing there to be decimal digits. Basically, as far as I can tell format-number() can only be used to pad numbers with zero digits, not with any other character.
