div

Divide two double-precision floating-point numbers.

Usage

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

div( x, y )

Divides two double-precision floating-point numbers.

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

v = div( 2.0, 5.0 );
// returns 0.4

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

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

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

Examples

var rand = require( '@stdlib/random/base/discrete-uniform' );
var div = require( '@stdlib/math/base/ops/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, div( x, y ) );
}

C APIs

Usage

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

stdlib_base_div( x, y )

Divides two double-precision floating-point numbers.

double v = stdlib_base_div( -5.0, 2.0 );
// returns -2.5

The function accepts the following arguments:

x: [in] double first input value (dividend).
y: [in] double second input value (divisor).

double stdlib_base_div( const double x, const double y );

Examples

#include "stdlib/math/base/ops/div.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, -5.0, 0.0/0.0 };

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