SLAX Example
The following code snippet lists the defaults for the decimal-format parameters, and uses the defined decimal format in the format-number XPath function:
version 1.1;
decimal-format default-format {
decimal-separator "." ;
digit "#" ;
grouping-separator "," ;
infinity "Infinity" ;
minus-sign "-" ;
nan "NaN";
pattern-separator ";" ;
percent "%";
per-mille "\x2030";
zero-digit "0" ;
}
match / {
...
var $number = -14560302.5;
expr format-number($number, "###,###.00", "default-format");
}
/* output is -14,560,302.50 */
