xmlXPathError xsltFormatNumberConversion	(	xsltDecimalFormatPtr	self,
		xmlChar *	format,
		double	number,
		xmlChar **	result
	)

xsltFormatNumberConversion: : the decimal format : the format requested : the value to format

Devuelve:

: the place to ouput the result

format-number() uses the JDK 1.1 DecimalFormat class:

http://java.sun.com/products/jdk/1.1/docs/api/java.text.DecimalFormat.html

Structure:

pattern := subpattern{;subpattern} subpattern := {prefix}integer{.fraction}{suffix} prefix := '\u0000'..'\uFFFD' - specialCharacters suffix := '\u0000'..'\uFFFD' - specialCharacters integer := '#'* '0'* '0' fraction := '0'* '#'*

Notation: X* 0 or more instances of X (X | Y) either X or Y. X..Y any character from X up to Y, inclusive. S - T characters in S, except those in T

Special Characters:

Symbol Meaning 0 a digit # a digit, zero shows as absent . placeholder for decimal separator , placeholder for grouping separator. ; separates formats.

• default negative prefix. % multiply by 100 and show as percentage ? multiply by 1000 and show as per mille X any other characters can be used in the prefix or suffix ' used to quote special characters in a prefix or suffix.

Returns a possible XPath error

void xsltNumberFormat	(	xsltTransformContextPtr	ctxt,
		xsltNumberDataPtr	data,
		xmlNodePtr	node
	)

xsltNumberFormat: : the XSLT transformation context : the formatting informations : the data to format

Convert one number.
