About stdlib...

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!

NPM version Build Status Coverage Status

Base 10 exponential function.

Installation

npm install @stdlib/math-base-special-exp10

Alternatively,

  • To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
  • If you are using Deno, visit the deno branch (see README for usage intructions).
  • For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var exp10 = require( '@stdlib/math-base-special-exp10' );

exp10( x )

Evaluates the base 10 exponential function.

var v = exp10( 3.0 );
// returns 1000.0

v = exp10( -9.0 );
// returns 1.0e-9

v = exp10( 0.0 );
// returns 1.0

v = exp10( NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random-base-randu' );
var exp10 = require( '@stdlib/math-base-special-exp10' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = (randu()*100.0) - 50.0;
    console.log( '10^%d = %d', x, exp10( x ) );
}

C APIs

Usage

#include "stdlib/math/base/special/exp10.h"

stdlib_base_exp10( x )

Evaluates the base 10 exponential function.

double out = stdlib_base_exp10( 3.0 );
// returns 1000.0

out = stdlib_base_exp10( -9.0 );
// returns 1.0e-9

The function accepts the following arguments:

  • x: [in] double input value.
double stdlib_base_exp10( const double x );

Examples

#include "stdlib/math/base/special/exp10.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 ) - 50.0;
        v = stdlib_base_exp10( x );
        printf( "10^%lf = %lf\n", x, v );
    }
}
