nanmin

Return the minimum value, ignoring NaN.

Usage

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

nanmin( x, y )

Returns the minimum value.

var v = nanmin( 4.2, 3.14 );
// returns 3.14

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

If any argument is NaN, the function returns the other operand.

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

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

If both arguments are NaN, the function returns NaN.

var v = nanmin( NaN, NaN );
// returns NaN

Examples

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

var m = nanmin( 3.0, 4.0 );
console.log( m );
// => 3.0

m = nanmin( NaN, 4.0 );
console.log( m );
// => 4.0

m = nanmin( 4.0, NaN );
console.log( m );
// => 4.0

m = nanmin( NaN, NaN );
console.log( m );
// => NaN

C APIs

Usage

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

stdlib_base_nanmin( x, y )

Returns the minimum value, ignoring NaN.

double out = stdlib_base_nanmin( 4.2, 3.14 );
// returns 3.14

out = stdlib_base_nanmin( 4.14, 0.0 / 0.0 );
// returns 4.14

The function accepts the following arguments:

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

double stdlib_base_nanmin( const double x, const double y );

Examples

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

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

    double v;
    int i;
    for ( i = 0; i < 10; i++ ) {
        v = stdlib_base_nanmin( x[i], y[i] );
        printf( "x[ %d ]: %lf, y[ %d ]: %lf, nanmin( x[ %d ], y[ %d ] ): %lf\n", i, x[ i ], i, y[ i ], i, i, v );
    }
