    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".

    mathvariant
    This attribute specifies the logical class of the number which varies in typography.

The following values are allowed:

    Gecko-specific notes

    • Starting with Gecko 20.0 (Firefox 20.0 / Thunderbird 20.0 / SeaMonkey 2.17) a unitless value for mathsize is allowed.
    • Some mathvariant values are only implemented starting with Gecko 28.0 (Firefox 28.0 / Thunderbird 28.0 / SeaMonkey 2.25) and require appropriate math fonts.
