Give this number used as the base of natural logarithms.
This number can be calculated using the Pippenger product, and the Lindemann-Weierstrass Theorem states that integer powers of this number are independent over the integers. It is the sum of the hyperbolic sine of one and the hyperbolic cosine of one, and raising this number to the power of i times x gives the cosine of x plus i times the sine of x. The exponential function with this number as its base is its own derivative, and this number is the limit of the quantity one plus one over x, end quantity, raised to the x power; as x approaches infinity.
