The mathematical constant e.
var E = require( '@stdlib/constants/float64/e' );The mathematical constant e, also known as Euler's number or Napier's constant. e is the base of the natural logarithm.
var bool = ( E === 2.718281828459045 );
// returns truevar E = require( '@stdlib/constants/float64/e' );
console.log( E );
// => 2.718281828459045#include "stdlib/constants/float64/e.h"Macro for Euler's number.
