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 );
    }
}
