About the Square Root Radical black outline icon
The mathematical radical sign: a short entry stroke, a sharp V descending to a point, then a steep rise into a long horizontal vinculum that extends to the right, ready to cover a number or expression. Use it in calculator interfaces, math education apps, formula editors, engineering and CAD tools, exam or tutoring materials and STEM presentation slides.
Strokes are uniform in weight and the overbar runs flat and long, so the sign still reads when a value is typeset beneath it. It pairs with plus, minus, sigma and percent operators in a math set. Align it to the same baseline as adjacent digits.
This is the black outline version of the square root radical icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
