public class BreakBinarySubtraction : OpenXmlLeafElement

[ISO/IEC 29500-1 1st Edition]

brkBinSub (Break on Binary Subtraction)

This element specifies how the subtraction operator is treated when it coincides with a line break, when brkBin is set to repeat. If this element is omitted, the subtraction operator is repeated before and after the break.

Whether the element is absent or present without the val attribute, the default of the val attribute is --.

[Example: The XML below demonstrates brkBinSub in use under mathPr:

<m:mathPr>
  <m:mathFont m:val="Cambria Math"/>
  <m:brkBin m:val="before"/>
  <m:brkBinSub m:val="--"/>
  <m:smallFrac m:val="0"/>
  <m:dispDef/>
  <m:lMargin m:val="0"/>
  <m:rMargin m:val="0"/>
  <m:defJc m:val="centerGroup"/>
  <m:wrapIndent m:val="1440"/>
  <m:intLim m:val="subSup"/>
  <m:naryLim m:val="undOvr"/>
</m:mathPr>

end example]

[Example:

Given the following XML representation using brkBinSub:

<m:brkBinSub m:val="-+"/>

Because the document option for break on binary subtraction is set to -+, any breaks in Math paragraphs on subtraction operators will display a – on the line before the break and a + on the line after the break.

end example]
