Some numbers are so distinctive they convey a lot of information about the domain of conversation around where they occur in text or source code. For instance, <math>pi</math> and Planck's constant are individually recognizable, although in the case of Planck's constant some knowledge of Physics is required. Other numbers may only become distinctive when combined together into a set of numbers, for instance there is nothing special about 0.5 until it is combined with half-a-dozen other numbers that are used to calculate sine/cosine using a Chebyshev series.

This Wiki is an attempt to collect together distinctive numbers.
