# @stdlib/math-base-special-fast-max

0.3.0 • Public • Published

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-fast-max`

## Usage

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

#### max( x, y )

Returns the maximum value.

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

## Notes

• The implementation ignores the sign of `0`.

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

v = max( -0.0, +0.0 );
// returns +0.0```
• The implementation does not check for `NaN` arguments.

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

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

## Examples

```var minstd = require( '@stdlib/random-base-minstd-shuffle' );
var max = require( '@stdlib/math-base-special-fast-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/fast/max.h"`

#### stdlib_base_fast_max( x, y )

Returns the maximum value.

```double out = stdlib_base_fast_max( 4.2, 3.14 );
// returns 4.2

out = stdlib_base_max_fast( 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_fast_max( const double x, const double y );`

### Examples

```#include "stdlib/math/base/special/fast/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 ) * 2000.0 ) - 1000.0;
y = ( ( (double)rand() / (double)RAND_MAX ) * 2000.0 ) - 1000.0;
v = stdlib_base_fast_max( x, y );
printf( "x: %lf, y: %lf, max(x, y): %lf\n", x, y, v );
}
}```

## Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
