C++ :: Converting Int To String Using Istringstream Inserts Commas

So I have a following function that converts int to string however it inserts the commas for thousands, millions, and so on. e.g. 65432 -> "65,432".

How do I make the conversion but have a string without commas?

I know it has to with locale but I cannot find it how to prevent it. Also I know about std::stoi() and atoi() but I do not want them.

Code:
template <typename T>
std::string NumberToString ( T Number ) {
std::stringstream ss;
ss << Number;
return ss.str();
}
