## Continued Fraction FunctionMath Arithmetic Class

```Public Function ContinuedFraction( _
ByVal vB As Variant _
, ByVal vA As Variant _
, ByVal vX As Variant _
, ByVal vN As Variant _
) As Variant```

### "Evaluate Continued Fraction" Evaluates the continued fraction illustrated below.

Continued fraction:
```                  A
B + ---------------------
A
B + ---------------
...
A
B + ---------
A
B + ---
X```

Examples:
```    ContinuedFraction(2, 3, 4, 0) = 4
ContinuedFraction(2, 3, 4, 1) = 2.75
ContinuedFraction(2, 3, 4, 2) = 3.09090909090909
ContinuedFraction(2, 3, 4, 3) = 2.97058823529412
ContinuedFraction(2, 3, 4, 4) = 3.00990099009901
ContinuedFraction(2, 3, 4, 5) = 2.99671052631579
ContinuedFraction(2, 3, 4, 6) = 3.00109769484083```
vB, vA, vX: Numeric values which are substituted into the above expression then evaluated. Function returns Null if any of these values are Null or cannot be fixed up to numbers.

vN: The number of divisions to perform within the continued fraction. vN defaults to 1 (one) if it is missing or Null or cannot be fixed up to a number. Function returns vX if vN is <= 0 (less than or equal to zero).
