var prices = [1.50, 10.00, 4.99, 2.30, 8.5]

let largePrices = prices.filter( { prices → Bool in
return prices > 3
})

print(largePrices)

print statement is this [10.0, 4.9900000000000002, 8.5]

why does it get that when thats not even in the array?

[shogunkaramazov]

@lac_ekim The print statement formats the array’s elements before printing them out in this case. If you want to get the exact value for each and every one of them, use a for in loop instead:

for price in largePrices {
  print(price)
}
