  • 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.
  • 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.
