Computes the minimum value of an array ignoring non-numeric values.

Installation

$ npm install compute-nanmin

For use in the browser, use browserify.

Usage

To use the module,

var min = require( 'compute-nanmin' );

min( arr )

Computes the minimum value of an array ignoring non-numeric values.

var data = [ 2, null, 5, 3, null, 7 ];

var val = min( data );
// returns 2

Note: if an input array does not contain any numeric values, the function returns null.

Examples

var min = require( 'compute-nanmin' );

// Simulate some data...
var data = new Array( 100 );
for ( var i = 0; i < data.length; i++ ) {
	// Every so often insert a missing value...
	if ( i%10 ) {
		data[ i ] = null;
	} else {
		data[ i ] = Math.round( Math.random()*100 );
	}
}
var val = min( data );
console.log( val );
