Topic:

<BOX> Math Box

Definition:

The BOX element is used for a variety of purposes:

• As invisible brackets for disambiguating expressions.
• For placing numerators over denominators, with or without dividing lines, corresponding to LaTeX's frac, atop and choose commands.
• For placing delimiters before, and/or after an expression, which grow to match the height of the expression. This corresponds to LaTeX's left and right commands.
• For stretchy integral and related signs that grow to match the height of the integrand. This goes beyond LaTeX and avoids the need for different symbols for different sizes of integral signs etc.

Attributes:

SIZE
This used to obtain oversized delimiters. The permitted values are normal (the default), medium, large and huge.
