```js
// до вызова
var menu = {
width: 200,
height: 300,
title: "My menu"
width: 200,
height: 300,
title: "My menu"
};
multiplyNumeric(menu);
// после вызова
menu = {
width: 400,
height: 600,
title: "My menu"
width: 400,
height: 600,
title: "My menu"
};
```
P.S. Для проверки на число используйте функцию:
```js
function isNumeric(n) {
function isNumeric(n) {
return !isNaN(parseFloat(n)) && isFinite(n)
}
```
