I really appreciate everything you have helped me with. Everything is
working with this, except 2 numbers...

When I plug in 1,000 and 999; I should be getting 6.24 and I get 6.54.

1,000/2 = 500 which should be 2.24
500/250 is 2*2 for 4.00

999/2 = 499.5 (in reality is 500) for 2.24
500/250 is 2*2 for 4.00
