This command differs among variants of English:

Center( <Conic> ): Returns the center of a circle, ellipse, or hyperbola.; Example: Center(x^2 + 4 y^2 + 2x - 8y + 1 = 0)
(, : Centre(x^2 + 4 y^2 + 2x - 8y + 1 = 0))
returns point A = (-1, 1)

,

Center( <Quadric> ): Creates the center of a quadric (e.g. sphere, cone, etc.).; Example:
Center(x^2 + (y-1)^2 + (z-2)^2 = 1) yields (0, 1, 2)
