LimitsPositioning

LimitsPositioning
is an option for UnderoverscriptBox and related boxes which specifies whether to change the positioning of underscripts and overscripts in the way conventional for limits.

MORE INFORMATION

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 which can be set to a list of forms for which LimitsPositioning->True should be used.

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
