The MathML REC describes:
|
|
|
|
The <mfrac> element is used for fractions. It can also be used to mark up
|
|
fraction-like objects such as binomial coefficients and Legendre symbols.
|
|
The syntax for <mfrac> is:
|
|
<mfrac> numerator denominator </mfrac>
|
|
|
|
Attributes of <mfrac>:
|
|
Name values default
|
|
linethickness number [ v-unit ] | thin | medium | thick 1
|
|
|
|
E.g.,
|
|
linethickness=2 actually means that linethickness=2*DEFAULT_THICKNESS
|
|
(DEFAULT_THICKNESS is not specified by MathML, see below.)
|
|
|
|
The linethickness attribute indicates the thickness of the horizontal
|
|
"fraction bar", or "rule", typically used to render fractions. A fraction
|
|
with linethickness="0" renders without the bar, and might be used within
|
|
binomial coefficients. A linethickness greater than one might be used with
|
|
nested fractions.
|
|
|
|
In general, the value of linethickness can be a number, as a multiplier
|
|
of the default thickness of the fraction bar (the default thickness is
|
|
not specified by MathML), or a number with a unit of vertical length (see
|
|
Section 2.3.3), or one of the keywords medium (same as 1), thin (thinner
|
|
than 1, otherwise up to the renderer), or thick (thicker than 1, otherwise
|
|
up to the renderer).
|
|
|
|
The <mfrac> element sets displaystyle to "false", or if it was already
|
|
false increments scriptlevel by 1, within numerator and denominator.
|
|
These attributes are inherited by every element from its rendering
|
|
environment, but can be set explicitly only on the <mstyle>
|
|
element.
