The mathematical constant e.
var e = require( '@stdlib/constants/math/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/math/float64-e' );
console.log( e );
// => 2.718281828459045
