## Constants

CatalanConstant

      CatalanConstant

  Catalan's Constant, approximately 0.915... It is defined to be the series where terms are `(-1^k)/((2*k+1)^2)`, where `k` ranges from 0 to infinity.

  See Wikipedia or Mathworld for more information.

EulerConstant

      EulerConstant

  Aliases: `gamma`

  Euler's constant gamma. Sometimes called the Euler-Mascheroni constant.

  See Wikipedia or Planetmath or Mathworld for more information.

GoldenRatio

      GoldenRatio

  The Golden Ratio.

  See Wikipedia or Planetmath or Mathworld for more information.

Gravity

      Gravity

  Free fall acceleration at sea level in meters per second squared. This is the standard gravity constant 9.80665. The gravity in your particular neck of the woods might be different due to different altitude and the fact that the earth is not perfectly round and uniform.

  See Wikipedia for more information.

e

      e

  The base of the natural logarithm. `e^x` is the exponential function `exp`. It is approximately 2.71828182846... This number is sometimes called Euler's number, although there are several numbers that are also called Euler's. An example is the gamma constant: `EulerConstant`.

  See Wikipedia or Planetmath or Mathworld for more information.

pi

      pi

  The number pi, that is the ratio of a circle's circumference to its diameter. This is approximately 3.14159265359...
