to_str
Description:
[ CCode ( cname = "g_ascii_dtostr" , instance_pos = -1 ) ]
public unowned string to_str (char[] buffer)
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.
Example: Double to string (with buffer):
public static int main (string[] args) {
// Output: ``20``
char[] buf = new char[double.DTOSTR_BUF_SIZE];
unowned string str = (20.0).to_str (buf);
print ("%s\n", str);
return 0;
}valac --pkg glib-2.0 double.to_str.valaParameters:
| buffer |
a buffer to place the resulting string in |
| buf_len |
the length of the buffer |
| d |
the value to convert |
Returns:
|
the pointer to the buffer with the converted string |
