Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Natural exponential function.
The natural exponential function is defined as
where e
is Euler's number.
npm install @stdlib/math-base-special-exp
var exp = require( '@stdlib/math-base-special-exp' );
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
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 ) );
}
#include "stdlib/math/base/special/exp.h"
Evaluates the natural exponential function.
double out = stdlib_base_exp( 4.0 );
// returns ~54.5982
out = stdlib_base_exp( -9.0 );
// returns ~1.234e-4
The function accepts the following arguments:
[in] double
input value.double stdlib_base_exp( const double x );
#include "stdlib/math/base/special/exp.h"
#include <stdlib.h>
#include <stdio.h>
int main( void ) {
double x;
double v;
int i;
for ( i = 0; i < 100; i++ ) {
x = ( (double)rand() / (double)RAND_MAX ) * 100.0;
v = stdlib_base_exp( x );
printf( "e^%lf = %lf\n", x, v );
}
}
