This example shows how to calculate the uniform series value using `payuni`.

The following cash flow represents the yearly income from an initial investment of \$10,000. The annual interest rate is 8%.

Year 1 - \$2000

Year 2 - \$1500

Year 3 - \$3000

Year 4 - \$3800

Year 5 - \$5000

To calculate the uniform series value:

`Series = payuni([-10000 2000 1500 3000 3800 5000], 0.08)`
```Series = 429.6296 ```
