In mathematics, the eccentricity of a conic section is a non-negative real number that uniquely characterizes its shape. One can think of the eccentricity as a measure of how much a conic section deviates from being circular.
Eccentricity: how much a conic section (a circle, ellipse, parabola or hyperbola) varies from being circular. A circle has an eccentricity of zero, so the eccentricity shows you how "un-circular" the curve is. Bigger eccentricities are less curved.

The meaning of ECCENTRICITY is the quality or state of being eccentric. How to use eccentricity in a sentence.
Eccentricity is the mathematical constant that is given for a conic section. It is the ratio of the distances from any point of the conic section to its focus to the same point to its corresponding directrix.
The eccentricity of an ellipse is a measure of how nearly circular the ellipse. Eccentricity is found by the following formula eccentricity = c/a where c is the distance from the center to the focus of the ellipse a is the distance from the center to a vertex.
The eccentricity of an ellipse measures how flattened a circle it is. It is equal to the square root of [1 - b*b/(a*a)]. The letter a stands for the semimajor axis, ½ the distance across the long axis of the ellipse. The letter b stands for the semiminor axis, ½ the distance across the short axis of the ellipse.
Eccentricity. The eccentricity of a conic section is a parameter that encodes the type of shape and is defined in terms of semimajor and semiminor axes as follows. The eccentricity can also be interpreted as the fraction of the distance along the semimajor axis at which the focus lies, (1)
