Frequently asked questions
What the Sigma Function icon means and where it's used, then how to install, style, label and license it.
The sigma-function icon represents a mathematical function, specifically the sigma symbol, commonly used in mathematics to denote summation. This icon signifies a calculation or mathematical operation, often used in educational or scientific contexts. The sigma symbol is widely recognized in mathematics and statistics.
In real-world applications, the sigma-function icon appears in various educational and scientific software, such as graphing calculators, mathematical modeling tools, or statistical analysis software. For instance, in computer algebra systems like Mathematica or Maple, similar icons are used to represent mathematical functions. In spreadsheet software like Microsoft Excel, the icon may be used to denote summation functions.
From a UX perspective, the sigma-function icon effectively communicates to users that a mathematical operation or calculation is involved. The icon's design should be clear and recognizable, ensuring that users understand its purpose and can use it effectively in mathematical or scientific contexts.
Sigma Function is one of 1,682 icons in Iconoir, made by Luca Burgio and released under MIT. It is drawn on a 24 × 24 grid with a 1.5 stroke.
Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds SigmaFunctionIcon to components/icons/iconoir-sigma-function.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.
Copy it as React (from Get icon, or the Code section): a typed SigmaFunctionIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.
Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.
With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Sigma Function icon, or any of 1,682 Iconoir icons, and install it from a prompt.
It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.
Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.
Sigma Function is a line icon drawn with a stroke width of 1.5. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.
Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.
Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Sigma Function", so screen readers say what it does.
Yes. SigmaFunctionIcon passes every SVG prop to the svg element, so <SigmaFunctionIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.
Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.
Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.
No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Iconoir, Luca Burgio and the license.
Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
Its tags are education, science, math, calculation, mathematics and formula. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Sigma Function in another set.
Iconoir draws many icons in several styles: Solid next to the default. Open the library and pick a style above the grid to see Sigma Function's siblings in it.
