Long Right Arrow in LaTeX (\longrightarrow)

Where it is used

Draws a long single right arrow, often for convergence statements and arrows between long expressions.

Writers use \longrightarrow when a short \to looks cramped, for instance in a_n \longrightarrow L or between two long terms in a reduction. A condition under the arrow can be added with \xrightarrow[n \to \infty]{}, which stretches to the label, or with \underset{n\to\infty}{\longrightarrow}. Chemistry uses long arrows for reactions with conditions written above. It is a fixed-length symbol, unlike the extensible arrows. The double version is \Longrightarrow, which is what \implies prints with extra spacing.

Frequently asked questions

How do I write Long Right Arrow in LaTeX?

Type \longrightarrow in math mode, for example $a_n \xrightarrow{n \to \infty} 0, \quad f_n \longrightarrow f$. It works in plain LaTeX without loading any package.

Which package do I need for \longrightarrow?

None. \longrightarrow is part of standard LaTeX, so it compiles with nothing in the preamble but the document class.

Can I use \longrightarrow in text mode, or only in math mode?

Only in math mode. Outside $...$ LaTeX stops with "Missing $ inserted", so write $\longrightarrow$ in running text. If you only need the glyph in text, paste the Unicode character ⟶ instead (with XeLaTeX or LuaLaTeX and a font that has it).
