LimitsPositioning
is an option for UnderoverscriptBox and related boxes that specifies whether to change the positioning of underscripts and overscripts in the way conventional for limits.
Details
- UnderoverscriptBox[x,y,z,LimitsPositioning->False] is always displayed with explicit underscripts and overscripts as
. - UnderoverscriptBox[x,y,z,LimitsPositioning->True] is displayed as
when large, and 
when small. - The
form is used when the box appears in a subscript or other script, or inline in a piece of text. - With the default setting LimitsPositioning->Automatic, the display of UnderoverscriptBox[x,y,z] depends on x. If x is ∖[Sum], ∖[Product], or another form conventionally displayed with limits, then LimitsPositioning->True is effectively used. Otherwise, LimitsPositioning->False is used.
- LimitsPositioningTokens is a Cell option that can be set to a list of forms for which LimitsPositioning->True should be used.
Examples
Basic Examples (1)
Define a low-level structure that has small underoverscript elements:
With LimitsPositioning->True, the upper and lower scripts go to the right of the base:
With LimitsPositioning->False, the upper and lower scripts stay directly above and below:
With LimitsPositioning->Automatic, the side positions are used with base 
, not with x:
