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

Compute the sum of two double-precision floating-point numbers.

Installation

npm install @stdlib/math-base-ops-add

Usage

var add = require( '@stdlib/math-base-ops-add' );

add( x, y )

Computes the sum of two double-precision floating-point numbers.

var v = add( -1.0, 5.0 );
// returns 4.0

v = add( 2.0, 5.0 );
// returns 7.0

v = add( 0.0, 5.0 );
// returns 5.0

v = add( -0.0, 0.0 );
// returns 0.0

v = add( NaN, NaN );
// returns NaN

Examples

var rand = require( '@stdlib/random-base-discrete-uniform' );
var add = require( '@stdlib/math-base-ops-add' );

var x;
var y;
var i;

for ( i = 0; i < 100; i++ ) {
    x = rand( -50, 50 );
    y = rand( -50, 50 );
    console.log( '%d + %d = %d', x, y, add( x, y ) );
}

C APIs

Usage

#include "stdlib/math/base/ops/add.h"

stdlib_base_add( x, y )

Computes the sum of two double-precision floating-point numbers.

double v = stdlib_base_add( -5.0, 2.0 );
// returns -3.0

The function accepts the following arguments:

  • x: [in] double first input value.
  • y: [in] double second input value.
double stdlib_base_add( const double x, const double y );

Examples

#include "stdlib/math/base/ops/add.h"
#include <stdio.h>

int main( void ) {
    const double x[] = { 3.14, -3.14, 0.0, 0.0/0.0 };
    const double y[] = { 3.14, -3.14, -0.0, 0.0/0.0 };

    double z;
    int i;
    for ( i = 0; i < 4; i++ ) {
        z = stdlib_base_add( x[ i ], y[ i ] );
        printf( "%lf + %lf = %lf\n", x[ i ], y[ i ], z );
    }
}
