mathematical monospace small f

Mathematical Monospace Small F

632/996

𝚏 is the lowercase Latin f in a mathematical monospace alphabet; in notation, its style can distinguish a variable or technical token. It has no fixed value by itself; the surrounding expression gives it a role. Some text-cleanup routines turn it into ordinary f, which strips the style distinction.

Text symbol

What 𝚏 means

It marks an f in the math-specific monospace alphabet.

Mathematical letters can look like font variants yet stand for different variables. A 1999 proposal for mathematical alphabets included monospace among styles used in scientific and technical publishing; encoding those styles lets plain text preserve the distinctions. The formula, not this letter alone, supplies its role.

How do I type 𝚏?

Use Unicode hexadecimal input or a character selector.

The exact steps depend on your operating system and the app receiving the character.

Technical and notation-focused.

Avoid using it as plain-text decoration; styled mathematical letters can complicate searching and restyling.

Why does 𝚏 show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
