Converting uint to string

[Chun Zhang]

Hi, All, 

I have a group of integers ranging from 1 to 2^32 that are in the format of uint32. I know strconv.Itoa(i) or strconv.FormatUint(i) can definitely give unique representation of each number. So, I can use it as the index of a map[string]interface{}.

However, I am wondering if I use string(i) only, will I get any two numbers the same string representation? My guess is no, but would like to get some comments from you experts.

Also, will string(i) be faster than strconv.Itoa or strcov.FormatUInt?

Thanks,

Chun

Assuming you mean 'to 2^32-1'.

You could also just the integers themselves as keys.
