About the Approximately Equal Double Tilde black filled icon

Two long wavy strokes sit one above the other with matching amplitude and spacing, drawing the approximately equal sign used in mathematics for rounded values, estimates and near matches. The curves are thin and horizontal, so the mark reads as typeset notation rather than decoration. Use it in math and science teaching materials, calculator and converter interfaces, currency and unit conversion screens, spec sheets that quote approximate figures, and data dashboards comparing similar values.

Both lines share the same length and shallow S-curve, and the even gap between them keeps the pair from merging into a single ripple. It belongs with the equals, not-equal, plus-minus, greater-than and less-than icons in the math operator set. Set it at text height next to numbers, and avoid sizes under 16 px where the waves flatten into straight lines.

This is the solid black filled version of the approximately equal double tilde icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
