GLib.KeyFile.prototype.get_double

function get_double(group_name: String, key: String): Number(gdouble) {
    // Gjs wrapper for g_key_file_get_double()
}

Returns the value associated with key under group_name as a double. If group_name is null, the start_group is used.

If key cannot be found then 0.0 is returned and @error is set to #G_KEY_FILE_ERROR_KEY_NOT_FOUND. Likewise, if the value associated with key cannot be interpreted as a double then 0.0 is returned and @error is set to #G_KEY_FILE_ERROR_INVALID_VALUE.

Since 2.12
