<mn>

The MathML <mn> element represents a numeric literal which is normally a sequence of digits with a possible separator (a dot or a comma). However,  it is also allowed to have arbitrary text in it which is actually a numeric quantity, for example "eleven".

displaystyle

A Boolean value specifying whether more vertical space is used for displayed equations or, if set to false, a more compact layout is used to display formulas. The main effect is that larger versions of operators are displayed, when displaystyle is set to true. See also movablelimits on <mo>.

mathvariant

This attribute specifies the logical class of the number which varies in typography. That is, although the names suggest the typographic style for the class, semantically, items with the same class are treated "the same" within an expression, which might or might not involve displaying them with the named typography. The following values are allowed:

  • normal (Default value) ; Example
  • bold ; Example
  • italic ; Example
  • bold-italic ; Example
  • double-struck ; Example
  • bold-fraktur ; Example
