add

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

Usage

var add = require( '@stdlib/number/float64/base/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 discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
var logEachMap = require( '@stdlib/console/log-each-map' );
var add = require( '@stdlib/number/float64/base/add' );

// Create arrays of random values:
var x = discreteUniform( 100, -50, 50 );
var y = discreteUniform( 100, -50, 50 );

// Perform element-wise addition:
logEachMap( '%d + %d = %d', x, y, add );

C APIs

Usage

#include "stdlib/number/float64/base/add.h"

stdlib_base_float64_add( x, y )

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

double v = stdlib_base_float64_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_float64_add( const double x, const double y );

Examples

#include "stdlib/number/float64/base/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_float64_add( x[ i ], y[ i ] );
        printf( "%lf + %lf = %lf\n", x[ i ], y[ i ], z );
    }
}
