addf

$NPM version$ $Build Status$ $Coverage Status$

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

Installation

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

Usage

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

addf( x, y )

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

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

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

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

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

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

Examples

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

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, addf( x, y ) );
}

C APIs

Usage

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

stdlib_base_addf( x, y )

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

float v = stdlib_base_addf( -5.0f, 2.0f );
// returns -3.0f

The function accepts the following arguments:

x: [in] float first input value.
y: [in] float second input value.

float stdlib_base_addf( const float x, const float y );

Examples

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

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

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

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
