Summary[edit]

Description
English: A squircle (blue) compared with a rounded square (red). A squircle is a mathematical curve defined by the equation x4+y4=r4, while a rounded square is four 90° circular arcs of the same radius connected by tangent straight lines. In this construction, the two curves are arranged to coincide at angles which are multiples of 45° (i.e. 0°, 45°, 90°, 135°, etc.).
