A number appearing in running prose.

This element is provided to allow numbers to be tagged so that the decimal separators and group separators appearing in them can be identified explicitly; this is helpful when the document is to be rendered in a style which may require different decimal or group separators

It is not, however, required that all numbers appearing in the document be tagged in this way. In some environments, the choice of decimal and group separators is fixed for all documents; in others, there is no requirement that the separators be changed. Even in environments where the element is used, numerals which are rendered without either a decimal or a group separator may typically remain untagged.


This element is part of the ISOSTS customization of the JATS journal publishing vocabulary; it is not part of the base vocabulary.

Example 1

	The classification includes all-weld metal properties obtained
	with a covered electrode as given below. The classification is
	based on an electrode size of <num dsep=",">4,0</num>&#160;mm,
	with the exception of the symbol for welding position, which
	is based on ISO&#160;15792-3. Where the defined diameter has
	not been manufactured, the closest diameter to 
	<num dsep=",">4,0</num>&#160;mm shall be used for all-weld 
	metal tests.</p>


Example 2

      <title>Combined control for the &ldquo;<italic>s</italic>&rdquo;
      method with ...</title>
	<p>Negative values of <italic>Q</italic> correspond to
	  estimates of the process fraction nonconforming in excess of
	  <num dsep=",">0,5 </num>at that specification limit and will
	  consequently always result in lot non-acceptance under the
	  provisions of this part of <std>ISO 3951</std>. 
	  For example, if ... 
	  then ...; entering 
	  <xref ref-type="table" rid="F1">Table F.1</xref> with 
	  <num dsep=",">0,135</num> gives an estimate of 
	  <num dsep="," gsep="&#160;">0,456&#160;9</num>; 
	  subtracting this from <num dsep=",">1,0</num> gives ...</p>
