Version 5.9.3

# `Math`

since version 5.9.2

Typeset a mathematical formula. The child elements are interpreted as MathML. The MathML root element `<math>` and the MathML namespace may be given, but both are optional; several child elements are treated as an implicit mrow. Experimental, implementation in progress.

## Child elements

MathML elements

## Parent elements

`A`, `B`, `Case`, `Color`, `Fontface`, `ForAll`, `I`, `Li`, `Loop`, `NoBreak`, `Otherwise`, `Paragraph`, `Span`, `U`, `URL`, `Until`, `While`

## Attributes

`display` (yes or no, optional)
  If `yes`, the formula is set in display style (more generous spacing, for example in fractions). If `no` (default), the formula is set in text style for inline use.
  - `yes`: Display style.
  - `no`: Inline style.
`fontfamily` (text, optional)
  Name of the font family (defined with `DefineFontfamily`) whose regular font provides the OpenType MATH table. The first `Math` element must set this attribute; later elements reuse the registered math font.

## Example

    <Paragraph>
      The Pythagorean theorem:
      <Math fontfamily="mathfont">
        <msup><mi>a</mi><mn>2</mn></msup>
        <mo>+</mo>
        <msup><mi>b</mi><mn>2</mn></msup>
        <mo>=</mo>
        <msup><mi>c</mi><mn>2</mn></msup>
      </Math>
    </Paragraph>
