SqrtBox

SqrtBox[x]
is a low-level box construct that represents the displayed object in notebook expressions.
  • Inside \(...\) SqrtBox[x] can be input as \@x.
  • In a notebook a SqrtBox can be created using Ctrl+2 or Ctrl+@. Ctrl+Space moves out from under the square root sign.
  • The baseline of SqrtBox[x] is taken to be the baseline of x.
  • If SqrtBox[x] does not fit on a single line, it is output as x^(1/2).
