public unowned string to_str (char[] buffer)
Converts a `gdouble` to a string, using the '.
' as decimal point.
This function generates enough precision that converting the string back using [func@GLib.ascii_strtod] gives the same machine-number (on machines with IEEE compatible 64bit doubles). It is guaranteed that the size of the resulting string will never be larger than [ const@GLib.ASCII_DTOSTR_BUF_SIZE] bytes, including the terminating nul character, which is always added.
