Re: Extracting Unique Characters from a Array

I have a array of numbers and I need only the unique elements to be retained.

Can you post the array you are working with?
And if you want your array to be in numerical order, you should read up on sort.

The numerical data I am working with are the part numbers. They will be nothing but 4 digit numbers, followed by a decimal point and followed by another 4 digits. Here they are 7742.8858 7748.5855 5581.2272 1248.2257 6589.5586 5680.1886 8762.1898 5535.5795 6896.6571 6573.2575 5487.3275 5489.5633 I am just pasting few for your reference. The numbers goes on..on and on... I know this array has to be sorted but I am not able to work further removing the repeating entries. Thank you for your immediate response.	[reply]
