    In other words, the n th digit of this number is 1 only if n is one of 1! = 1, 2! = 2, 3! = 6, 4! = 24, etc. Liouville showed that this number belongs to a class of transcendental numbers that can be more closely approximated by rational numbers than can any irrational algebraic number, and this class of numbers is called the Liouville numbers ...

    The total time is 1.1191 + 0.8672 = 1.9863 The conclusion, based on this particular model, is that equation 6 is slightly faster than equation 5, regardless of the fact that equation 6 has more terms. This result is typical of the general trend.

    The computation of (1 + ⁠ iπ / N ⁠) N is displayed as the combined effect of N repeated multiplications in the complex plane, with the final point being the actual value of (1 + ⁠ iπ / N ⁠) N. It can be seen that as N gets larger (1 + ⁠ iπ / N ⁠) N approaches a limit of −1. Euler's identity asserts that is

  9. Mathematical constant - Wikipedia

    en.wikipedia.org/wiki/Mathematical_constant

    The circumference of a circle with diameter 1 is π.. A mathematical constant is a number whose value is fixed by an unambiguous definition, often referred to by a special symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems.
