Convert double to string

[JKop]

What's the best method to use?

I've searched the web a bit and all I've come up with is "sprintf".

Also, for the converse, ie. string to double, is "atof" the way to go?

Kind Regards,

JKop

Try the FAQ

You can use a string stream.

But apparently not the FAQ - usually a better place to start.

Again, a quick perusal of the FAQ would answer that:

Boost libraries are a good choice for simple conversions. Look for
lexical_cast. sstream is a good choice for formatted strings. ex: int +
string + anotherint + anotherstring : "12 eggs is the same as 1 dozen
eggs."

For a comparison of boost::lexical_cast and the various other options,
see Herb Sutter's article:
