About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

max

Return the maximum value.

Installation

npm install @stdlib/math-base-special-max

Usage

var max = require( '@stdlib/math-base-special-max' );

max( x, y )

Returns the maximum value.

var v = max( 4.2, 3.14 );
// returns 4.2

v = max( +0.0, -0.0 );
// returns +0.0

If any argument is NaN, the function returns NaN.

var v = max( 4.2, NaN );
// returns NaN

v = max( NaN, 3.14 );
// returns NaN

Examples

var minstd = require( '@stdlib/random-base-minstd-shuffle' );
var max = require( '@stdlib/math-base-special-max' );

var x;
var y;
var v;
var i;

for ( i = 0; i < 100; i++ ) {
    x = minstd();
    y = minstd();
    v = max( x, y );
    console.log( 'max(%d,%d) = %d', x, y, v );
}

C APIs

Usage

#include "stdlib/math/base/special/max.h"

stdlib_base_max( x, y )

Returns the maximum value.

double out = stdlib_base_max( 4.2, 3.14 );
// returns 4.2

out = stdlib_base_max( 0.0, -0.0 );
// returns 0.0

The function accepts the following arguments:

• x: [in] double input value.
• y: [in] double input value.

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

Examples

#include "stdlib/math/base/special/max.h"
#include <stdlib.h>
#include <stdio.h>

int main( void ) {
    double x;
    double y;
    double v;
    int i;
    
    for ( i = 0; i < 100; i++ ) {
        x = ( ( (double)rand() / (double)RAND_MAX ) * 200.0 ) - 100.0;
        y = ( ( (double)rand() / (double)RAND_MAX ) * 200.0 ) - 100.0;
        v = stdlib_base_max( x, y );
        printf( "x: %lf, y: %lf, max(x, y): %lf\n", x, y, v );
    }
}
