Just use '===' for comparing instead of '==' (Why?)

Try this,

(function(){

    var ZERO = 0;
    var currency= $(".currency").val();

    if(currency=== '' || currency.length === 0){
        $(".currency").val(ZERO.toFixed(2));
    }
    else if(currency!== '' || currency.length !== 0){
        $(".currency").val();
    }

}());
