Historical Note on Stirling's Constant

The name Stirling's constant has been coined by $\mathsf{Pr} \infty \mathsf{fWiki}$ for the square root of $2 \pi$ from its appearance in Stirling's Formula, where it can be seen to be:

$\ds \sqrt {2 \pi} = \lim_{n \mathop \to \infty} \dfrac {n! e^n} {n^n \sqrt n}$
