divf

Divide two single-precision floating-point numbers.

Usage

var divf = require( '@stdlib/number/float32/base/div' );

divf( x, y )

Divides two single-precision floating-point numbers.

var v = divf( -1.0, 5.0 );
// returns ~-0.2

v = divf( 2.0, 5.0 );
// returns ~0.4

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

v = divf( -0.0, 5.0 );
// returns -0.0

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

Examples

var rand = require( '@stdlib/random/base/discrete-uniform' );
var divf = require( '@stdlib/number/float32/base/div' );

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, divf( x, y ) );
}

C APIs

Usage

#include "stdlib/number/float32/base/div.h"

stdlib_base_float32_div( x, y )

Divides two single-precision floating-point numbers.

float v = stdlib_base_float32_div( -5.0f, 2.0f );
// returns -2.5f

The function accepts the following arguments:

  • x: [in] float first input value (dividend).
  • y: [in] float second input value (divisor).
float stdlib_base_float32_div( const float x, const float y );

Examples

#include "stdlib/number/float32/base/div.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, -5.0f, 0.0f/0.0f };

    float z;
    int i;
    for ( i = 0; i < 4; i++ ) {
        z = stdlib_base_float32_div( x[ i ], y[ i ] );
        printf( "%f / %f = %f\n", x[ i ], y[ i ], z );
    }
}
