MathML defines a list of horizontally stretched operators that are
stretched horizontally to match the maximum width of expression
placed above or below. Here are some examples:
- Arrows: ←, → and ↔
- Double Arrows: ⇐, ⇒ and ⇔
- Overline and Underline: ‾ and _
- Horizontal Parentheses: ⏜ and ⏝
- Horizontal Brackets: ⏞, ⏟, ⎴ and ⎵
- Tilde and Hat: ~ and ^
The example below shows 4 horizontally stretched operators:
<math><mover><mrow><mi>A</mi><mi>B</mi></mrow><mo>→</mo></mover> <mo>≠</mo>
<munder><mrow><mi>A</mi><mi>B</mi></mrow><mo>_</mo></munder> <mo>≠</mo>
<mover><mrow><mi>A</mi><mi>B</mi></mrow><mo>⏜</mo></mover> <mo>≠</mo>
<munder><mrow><mi>A</mi><mi>B</mi></mrow><mo>⏟</mo></munder>
</math>
