FAQ
Answered from function's own facts: its shelf, the weights it was drawn in, its siblings and its dates.
- What is the function icon for?
- The function sign, for formulas, computed fields, scripts and calculated values. It is filed under Math in Keyline Icons, drawn on the same 24×24 grid as the rest of the set. People look for it as function, formula, fx, math, calculate, expression and script, and the browser's search matches all of those.
- What styles does the function icon come in?
- All four: stroke, two-tone, duotone and fill. They are drawn from the same geometry, so swapping style never moves anything.
- Is there a square or circle version of function?
- Yes. The same drawing is also boxed, as square-function and circle-function. Each is its own icon with its own name.
- What other icons go with function?
- angle, asterisk, brace-left, brace-right, braces and braces-ellipsis, and 12 more, all shown below. They are the Math shelf: nothing else in the set is named after function.
- How do I import function in React?
- <Function /> is the component, and the weight decides the module: stroke from "@keyline-icons/react", two-tone from "@keyline-icons/react/two-tone", duotone from "@keyline-icons/react/duotone" and fill from "@keyline-icons/react/fill". It takes the usual SVG props plus a size, so <Function size={16} /> and className="size-4" both work, and there is no provider or theme to set up.
- Where is the function SVG?
- icons/stroke/function.svg, icons/two-tone/function.svg, icons/duotone/function.svg and icons/fill/function.svg in the repository, normalised: no wrapper, no ids and no classes to strip out. The tabs above hand you the same drawing as SVG or JSX without the download, and neither needs an install.
- When was function added to the set?
- Added 20 Oct 2026. It ships in v2.1.0, so an install at that version or later has it.
Questions about the set rather than about this drawing are answered where they belong. The home page covers what the set is, how the three styles differ, why some icons come boxed and where the Figma file is; installing the set in a shadcn/ui project covers the React package, the CLI and using an icon without React. The MIT licence is stated in the footer of every page.
