Absolute Value Delimiter \abs

When to use Absolute Value Delimiter

Typesets automatically sized absolute-value delimiters. In source, start from the exact \abs 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

\abs

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

Example

\abs{\frac{x}{y}}

Rendered output

absolute value

Copy and compatibility checks

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