XML Numeric Values Format Specification

---

These qualifiers are used to customize the encoding format of numeric values (XSD double, decimal, or float types). It is sometimes necessary to have numbers formatted in a certain way (for example, a decimal value format such as"+0012.00"). By default, all leading and trailing zeros are omitted, as well as the positive sign, so the value above will be encoded as "12". It is possible using these qualifiers to specify the exact required format of such values. This can be done at any scope - global, schema or node. To customize the format of all decimal, double or float values at the global or schema level, use the <decimalFormat>, <doubleFormat> and <floatFormat> configuration elements respectively. For the node scope, use <numericFormat> element.

Usage

<decimalFormat | doubleFormat | floatFormat | numericFormat
 
	[totalDigits="xs:byte"]
 
	[fractionDigits="xs:byte"]
 
	[fractionMinDigits="xs:byte"]
 
	[integerMaxDigits="xs:byte"]
 
	[integerMinDigits="xs:byte"]
 
	[expSymbol="xs:token"]
 
	[expMinValue="xs:short"]
 
	[expMaxValue="xs:short"]
 
	[expDigits="xs:byte"]
 
	[signPresent="xs:boolean"]
 
	[pointPresent="xs:boolean"]
 
	[expSignPresent="xs:boolean"]
 
	[expPresent="xs:boolean"]

All attr

Attribute name	Applicable types	Description
totalDigits	double float decimal	Number of total significiant digits. Trailing and leading zeros are not counted by this parameter.
fractionDigits	double float decimal	Number of maximum signficiant digits in fraction part, precision.
fractionMinDigits	double float decimal	Number of minimum digits in the fraction part. If the fraction part has less digits than this parameter then trailing zeros will be added.
integerMaxDigits	double float decimal	Maximum digits in integer part; if it is 0 and integer part is 0 then integer part will be omitted, for example .3, or -.3.
integerMinDigits	double float decimal	Minimum digits in integer part, leading zeros will be added if necessary.
expSymbol	double float	Exponent symbol. 'E' or 'e' only; 0 if no exponent is expected.
expMinValue	double float	Minimum exponent value. By default, -infinity.
expMaxValue	double float	Maximum exponent value. By default, infinity.
expDigits	double float	Number of digits in exponent part; if exponent's value is not enough, trailing zeros will be added.
signPresent	double float decimal	Indicates ("true" or "false"), sign must be present, even if value is positive.
pointPresent	double float decimal	Indicates ("true" or "false"), decimal point must be present, even if value's fraction is 0
expPresent	double float	Indicates ("true" or "false"), exponent must be present, even if its value is 0.
expSignPresent	double float	Indicates ("true" or "false"), exponent sign must be present, even if its value is positive.

ibutes are optional, the order is not important.

So, to format a decimal value "12" as "+0012.00" the configuration element for node should look as follows:

<numericFormat fractionMinDigits="2" integerMinDigits="4" signPresent="true"/>
