DocumentBase.OMathBreakBin Property


Gets or sets a value that specifies where Microsoft Office Word places binary operators when equations span two or more lines.

Namespace:   Microsoft.Office.Tools.Word
Assembly:  Microsoft.Office.Tools.Word.v4.0.Utilities (in Microsoft.Office.Tools.Word.v4.0.Utilities.dll)

public WdOMathBreakBin OMathBreakBin { get; set; }

Property Value

Type: Microsoft.Office.Interop.Word.WdOMathBreakBin

One of the WdOMathBreakBin values.

When the equation breaks on a binary operator—for example, an addition, subtraction, or multiplication operator—there are three different placements of the operator: before the break, after the break, and repeated both before and after the break.

When this property is set to wdOMathBreakBinRepeat, use the OMathBreakSub property to specify how Word treats subtraction operators that appear before a line break.

The following code example sets the OMathBreakBin property to a value that causes the binary operator that the equation breaks on to repeat at the beginning of the new line. In addition, the code sets the OMathBreakSub property to a value that converts the sequence of two subtraction operators to a sequence of a plus operator followed by a minus operator. This prevents double negatives from being created when the OMathBreakBin property is set to wdOMathBreakBinRepeat, which repeats the subtraction operator at the equation break. To use this example, run it from the ThisDocument class in a document-level project.

private void SetEquationBinaryOperatorBreak()
    this.OMathBreakBin = Word.WdOMathBreakBin.wdOMathBreakBinRepeat;
    this.OMathBreakSub = Word.WdOMathBreakSub.wdOMathBreakSubPlusMinus;
