Converting a float to a string

[timmay3141]

How can I convert a float to a string? I could convert an int to a string via itoa, but no ftoi exists. Any thoughts?

Check the MSDN documentation on sprintf.

CString::Format should also work.

Or even check the _fcvt function in msdn.

_fcvt : Converts a floating-point number to a string.

you can use the function "sprintf" do it.
here is an example:

char str[20] = {0};
float num = 7.9f;
sprintf( str, "%f", num );

... or try

std::string ftoa ( float f )

as a more modern way.

Or std::stringstream, supported by the C++ Standard.

Or boost::lexical_cast, a convenient wrapper around that use of std::stringstream (

http://www.boost.org).
