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".

Attributes

class, id, style
Provided for use with stylesheets.
dir
The text direction. Possible values are either ltr (left to right) or rtl (right to left).
href

mathbackground
The background color. You can use #rgb, #rrggbb and HTML color names.
mathcolor
The text color. You can use #rgb, #rrggbb and HTML color names.

The size of the content. Possible values are:
  • small: Font is rendered smaller than the current font size.
  • normal: Equivalent to 100% or 1em.
  • bigFont is rendered larger than the current font size.
  • a custom length.
  • or a unitless value which multiplies the default.
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
