EULERGAMMA

The Euler-Mascheroni constant.

The Euler-Mascheroni constant gamma (also known as "Euler's constant" or "the Euler constant") is defined as the limit of the sequence

$$\gamma = \lim_{n\to\infty} \left( \sum_{k=1}^n \frac{1}{k} - \ln n \right)$$

Usage

var EULERGAMMA = require( '@stdlib/constants/float64/eulergamma' );

var bool = ( EULERGAMMA === 0.5772156649015329 );
// returns true

var EULERGAMMA = require( '@stdlib/constants/float64/eulergamma' );

console.log( EULERGAMMA );
// => 0.5772156649015329
