# Converting VBScript's Log Function

**Definition**: Returns the natural logarithm of a number.

### Log

Most people probably have the natural logarithms for all known numbers committed to memory. If you don't, and you need to know the log for a particular number, then use the System.Math class and the **Log** method. This command returns the log of 100 and assigns the value to the variable $a:

```
$a = [math]::log(100)
```

When you run this command and then echo back the value of $a you should get the following:

```
4.60517018598809
```
