Ceiling Delimiter \ceil

When to use Ceiling Delimiter

Typesets automatically sized ceiling brackets. In source, start from the exact \ceil 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

\ceil

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

\ceil{\frac n2}

Rendered output

ceiling of n over two

Copy and compatibility checks

• Copy \ceil 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.
