`LOG`

computes the logarithm of an expression.

NUMBER

```
LOG(n2, n1)
```

`n2`

is the base by which to compute the logarithm.

`n1`

is the value whose logarithm is calculated. It can be any numeric expression that is greater than zero. When the value is equal to or less than zero, `LOG`

returns a null value.

`LOG(10,100)`

returns the value `2`
