_Document.OMathBreakSub property

Office 2013 and later

Returns or sets a WdOMathBreakSub enumeration value that represents how Microsoft Office Word handles a subtraction operator that falls before a line break. Read/write.

Namespace:  Microsoft.Office.Interop.Word
Assembly:  Microsoft.Office.Interop.Word (in Microsoft.Office.Interop.Word.dll)

WdOMathBreakSub OMathBreakSub { get; set; }

This property is used only when the OMathBreakBin property is set to wdOMathBreakBinRepeat. Subtraction sometimes receives special treatment when a line break falls on a subtraction operator and the document setting is to repeat the subtraction operator on the following line, because two negatives make a positive. Some writers choose to convert one of the minus signs into a plus sign, and some choose to keep the two negatives.
