Generalized Fraction \genfrac

When to use Generalized Fraction

Builds a fraction with configurable delimiters, rule, and style. In source, start from the exact \genfrac command instead of imitating the rendered glyph with Unicode characters or manual spacing. This keeps the expression editable and gives the renderer enough structure to apply mathematical spacing correctly.

Syntax

\genfrac

The documented syntax belongs to amsmath. Keep every required argument, brace pair, and environment boundary intact when moving the command between an editor, Markdown processor, notebook, or publishing system.

Example

\genfrac{(}{)}{0pt}{}{n}{k}

Rendered output

parenthesized fraction

Copy and compatibility checks

• Copy \genfrac exactly; changing its case or removing a leading backslash can turn it into plain text.
• Confirm that the destination loads amsmath before relying on this command.
• Render the example once, then inspect grouping, limits, scripts, and spacing before publishing.
