## Log N Real FunctionMath Reals Class

```Public Function LogNReal( _
ByVal vX As Variant _
, ByVal vY As Variant _
) As Variant```

### "Log Base N Of Real Number" Return the base Y logarithm of X, where both arguments are real numbers.

Examples:
```    LogNReal(0, 10) = 0
LogNReal(10, 10) = 1
LogNReal(12, 10) = 1.07918124604762
LogNReal(16, 10) = 1.20411998265592
LogNReal(167, 10) = 2.22271647114758```
v1.5 BugFix: Corrected the LogNReal(0, 10) example above to show the correct result.

Note: The LogBaseN function supports both real AND complex numbers.
Note: Function generates an "Invalid Procedure Call" error if either argument is < 0 (less than zero).

vX: The number whose base vY logarithm is to be returned. Function returns Null if vX is Null or cannot be fixed up to a number.

vY: The logarithm base. Function returns Null if vY is Null or cannot be fixed up to a number.
