About the Approximately Equal black filled icon
Two parallel wavy strokes, stacked one above the other, spell out the double tilde that mathematicians read as approximately equal to. The tapered curves give the sign real weight instead of leaving it a thin squiggle. Use it in formula editors, calculator and unit converter interfaces, rounding or estimate labels, school worksheets, statistics slides and engineering tolerance notes.
Both strokes share the same amplitude and taper toward flattened ends, and the gap between them matches the spacing of a standard equals sign. It lines up with plus, minus, equals and not-equal marks in a math set; center it on the text baseline when placed inline.
This is the solid black filled version of the approximately equal icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
