addf
Compute the sum of two single-precision floating-point numbers.
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 );
}
