I have an array that randomly gets a coin put into it (denominations: 0.01, 0.05, 0.10, 0.25). The array is a Double array. It seems to work, but at times values get added that look like this:

[0.050000000000000003]
[0.050000000000000003, 0.01]
[0.050000000000000003, 0.01, 0.10000000000000001]

I'm not sure what I'm doing wrong to have these extra zeros show up.

Thanks in advance for any help.

Excellent. Thank you so much for pointing me in the right direction. – OneFour Apr 18 '16 at 15:47
You could use an enum instead of raw numbers.enum Coins: Int { static var denominator = 100; case pence = 1; case five = 5; case ten = 10; case quarter = 25; } – Evdzhan Mustafa Apr 18 '16 at 15:51
All great answers. Thank you so much. – OneFour Apr 18 '16 at 16:01
