What's the easiest way to convert an uint64 value into a standart C++ string? I checked out the assign methods from the string and could find no one that accepts an uint64 (8 bytes) as argument.
How can I do this?
Thanks Nelson R. Pérez

more descriptive than streams I think is lexical_cast
uint64 somevalue;
string result = boost::lexical_cast<string>(somevalue);
#include <sstream>
std::ostringstream sin;
uint64 i;
sin << i;
std:string intAsString(oss.str());
The standard way:
std::string uint64_to_string( uint64 value ) {
std::ostringstream os;
os << value;
return os.str();
}
If you need an optimized method, then you may use this one:
void uint64_to_string( uint64 value, std::string& result ) {
result.clear();
result.reserve( 20 ); // max. 20 digits possible
uint64 q = value;
do {
result += "0123456789"[ q % 10 ];
q /= 10;
} while ( q );
std::reverse( result.begin(), result.end() );
}
std::string converted(reinterpret_cast<char*>(&my_int64), reinterpret_cast<char*>((&my_int64)+1));
