minabs

Return the minimum absolute value.

Usage

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

minabs( x, y )

Returns the minimum absolute value.

var v = minabs( -4.2, 3.14 );
// returns 3.14

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

If any argument is NaN, the function returns NaN.

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

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

Examples

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

var opts = {
    'dtype': 'float64'
};
var x = uniform( 100, -500.0, 500.0, opts );
var y = uniform( 100, -500.0, 500.0, opts );

logEachMap( 'minabs(%0.4f,%0.4f) = %0.4f', x, y, minabs );

C APIs

Usage

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

stdlib_base_minabs( x, y )

Returns the minimum absolute value.

double out = stdlib_base_minabs( -4.2, 3.14 );
// returns 3.14

out = stdlib_base_minabs( 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_minabs( const double x, const double y );

Examples

#include "stdlib/math/base/special/minabs.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 ) * 1000.0 ) - 500.0;
        y = ( ( (double)rand() / (double)RAND_MAX ) * 1000.0 ) - 500.0;
        v = stdlib_base_minabs( x, y );
        printf( "x: %lf, y: %lf, minabs(x, y): %lf\n", x, y, v );
    }
}
