Natural Exponential Function
Natural exponential function.
The natural exponential function is defined as
where e
is Euler's number.
Installation
npm install @stdlib/math-base-special-exp
Usage
var exp = require( '@stdlib/math-base-special-exp' );
exp( x )
Evaluates the natural exponential function.
var v = exp( 4.0 );
// returns ~54.5982
v = exp( -9.0 );
// returns ~1.234e-4
v = exp( 0.0 );
// returns 1.0
v = exp( NaN );
// returns NaN
Examples
var randu = require( '@stdlib/random-base-randu' );
var exp = require( '@stdlib/math-base-special-exp' );
var x;
var i;
for ( i = 0; i < 100; i++ ) {
x = (randu()*100.0) - 50.0;
console.log( 'e^%d = %d', x, exp( x ) );
}
