add5

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

Usage

var add5 = require( '@stdlib/math/base/ops/add5' );

add5( x, y, z, w, u )

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

var v = add5( -1.0, 5.0, 2.0, -3.0, 4.0 );
// returns 7.0

v = add5( 2.0, 5.0, 2.0, -3.0, 4.0 );
// returns 10.0

v = add5( 0.0, 5.0, 2.0, -3.0, 4.0 );
// returns 8.0

v = add5( -0.0, 0.0, -0.0, -0.0, -0.0 );
// returns 0.0

v = add5( NaN, NaN, NaN, NaN, NaN );
// returns NaN

Examples

var rand = require( '@stdlib/random/base/discrete-uniform' ).factory;
var filledBy = require( '@stdlib/array/base/filled-by' );
var add5 = require( '@stdlib/math/base/ops/add5' );

var x = filledBy( 100, rand( -50, 50 ) );
var y = filledBy( x.length, rand( -50, 50 ) );
var z = filledBy( x.length, rand( -50, 50 ) );
var w = filledBy( x.length, rand( -50, 50 ) );
var u = filledBy( x.length, rand( -50, 50 ) );

var i;
for ( i = 0; i < x.length; i++ ) {
    console.log( '%d + %d + %d + %d + %d = %d', x[i], y[i], z[i], w[i], u[i], add5( x[i], y[i], z[i], w[i], u[i] ) );
}

C APIs

Usage

#include "stdlib/math/base/ops/add5.h"

stdlib_base_add5( x, y, z, w, u )

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

double out = stdlib_base_add5( -5.0, 2.0, 4.0, 3.0, 1.0 );
// returns 5.0

The function accepts the following arguments:

x: [in] double first input value.
y: [in] double second input value.
z: [in] double third input value.
w: [in] double fourth input value.
u: [in] double fifth input value.

double stdlib_base_add5( const double x, const double y, const double z, const double w, const double u );

Examples

#include "stdlib/math/base/ops/add5.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 };
    const double z[] = { 2.0, -3.0, -0.0, 0.0/0.0 };
    const double w[] = { 2.0, -3.0, -0.0, 0.0/0.0 };
    const double u[] = { -1.0, 4.0, 0.0, 0.0/0.0 };

    double out;
    int i;
    for ( i = 0; i < 4; i++ ) {
        out = stdlib_base_add5( x[ i ], y[ i ], z[ i ], w[ i ], u[ i ] );
        printf( "%lf + %lf + %lf + %lf + %lf = %lf\n", x[ i ], y[ i ], z[ i ], w[ i ], u[ i ], out );
