minabsf

Return the minimum absolute single-precision floating-point number.

Usage

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

minabsf( x, y )

Returns the minimum absolute single-precision floating-point number.

var v = minabsf( -4.0, 3.0 );
// returns 3.0

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

If any argument is NaN, the function returns NaN.

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

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

Examples

var randu = require( '@stdlib/random/array/uniform' );
var minabsf = require( '@stdlib/math/base/special/minabsf' );

var opts = {
    'dtype': 'float32'
};

var x = randu( 100, -500.0, 500.0, opts );
var y = randu( 100, -500.0, 500.0, opts );

var v;
var i;
for ( i = 0; i < 100; i++ ) {
    v = minabsf( x[ i ], y[ i ] );
    console.log( 'minabsf(%d,%d) = %d', x[ i ], y[ i ], v );
}

C APIs

Usage

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

stdlib_base_minabsf( x, y )

Returns the minimum absolute single-precision floating-point number.

float out = stdlib_base_minabsf( -4.2f, 3.14f );
// returns 3.14f

out = stdlib_base_minabsf( 0.0f, -0.0f );
// returns +0.0f

The function accepts the following arguments:

x: [in] float input value.
y: [in] float input value.

float stdlib_base_minabsf( const float x, const float y );

Examples

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

int main( void ) {
    float x;
    float y;
    float v;
    int i;

    for ( i = 0; i < 100; i++ ) {
        x = ( ( (float)rand() / (float)RAND_MAX ) * 1000.0f ) - 500.0f;
        y = ( ( (float)rand() / (float)RAND_MAX ) * 1000.0f ) - 500.0f;
        v = stdlib_base_minabsf( x, y );
        printf( "x: %f, y: %f, minabsf(x, y): %f\n", x, y, v );
    }
