minmaxf

Return the minimum and maximum of two single-precision floating-point numbers.

Installation

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

Usage

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

minmaxf( x, y )

Returns the minimum and maximum of two single-precision floating-point numbers in a single pass.

var v = minmaxf( 4.2, 3.14 );
// returns [ 3.14, 4.2 ]

v = minmaxf( +0.0, -0.0 );
// returns [ -0.0, +0.0 ]

If any argument is NaN, the function returns NaN for both the minimum value and the maximum value.

var v = minmaxf( 4.2, NaN );
// returns [ NaN, NaN ]

v = minmaxf( NaN, 3.14 );
// returns [ NaN, NaN ]

minmaxf.assign( x, y, out, stride, offset )

Returns the minimum and maximum of two single-precision floating-point numbers in a single pass and assigns results to a provided output array.

var Float32Array = require( '@stdlib/array-float32' );

var out = new Float32Array( 2 );

var v = minmaxf.assign( 5.0, -2.0, out, 1, 0 );
// returns <Float32Array>[ -2.0, 5.0 ]

var bool = ( v === out );
// returns true

Examples

var logEachMap = require( '@stdlib/console-log-each-map' );
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var minmaxf = require( '@stdlib/math-base-special-minmaxf' );

var opts = {
    'dtype': 'float32'
};
var x = discreteUniform( 100, -100, 100, opts );
var y = discreteUniform( 100, -100, 100, opts );

logEachMap( 'minmaxf(%d, %d) = [%s]', x, y, minmaxf );

C APIs

Usage

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

stdlib_base_minmaxf( x, y, &min, &max )

Evaluates the minimum and maximum of two single-precision floating-point numbers in a single pass.

float x = 3.14f;
float y = 2.71f;

float min;
float max;
stdlib_base_minmaxf( x, y, &min, &max );

The function accepts the following arguments:

• x: [in] float first number.
• y: [in] float second number.
• min: [out] float destination for the minimum value.
• max: [out] float destination for the maximum value.

void stdlib_base_minmaxf( const float x, const float y, float* min, float* max );

Examples

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

int main( void ) {
    const float x[] = { 1.0f, 0.45f, -0.89f, 0.0f / 0.0f, -0.78f, -0.22f, 0.66f, 0.11f, -0.55f, 0.0f };
    const float y[] = { -0.22f, 0.66f, 0.0f, -0.55f, 0.33f, 1.0f, 0.0f / 0.0f, 0.11f, 0.45f, -0.78f };

    float min;
    float max;
    int i;
    for ( i = 0; i < 10; i++ ) {
        stdlib_base_minmaxf( x[ i ], y[ i ], &min, &max );
        printf( "x: %f, y: %f => min: %f, max: %f\n", x[ i ], y[ i ], min, max );
    }
}
