问题描述:

I do not know how to format after multiplying.

Example:

0.012333 * 3.500

Always zero left would be a fee.

Is there a way to format this 0.012333 after multiplying?

As someone rightly noted in the comments section of your Post, the result of multiplying

`0.012333`

by`3.500`

would be`0.0431655`

. However, if byFormatYou want to mean Formatting the Result (`0.0431655`

) to some friendly-looking Figures, then you may want to consider working with PHP's`number_format()`

Function which will return a String, given a`Floating Point Number`

like`0.0431655`

. The Snippet below demonstrates this:

```
<?php
$result = 0.012333 * 3.500;
$formatted = number_format($result, 2, '.', ',');
var_dump($result); //<== YIELDS:: float 0.0431655
var_dump($formatted); //<== YIELDS:: string '0.04' (length=4)
```
