Check out g_snprintf in the glib reference manual (section: String Utility
Functions).  I believe you call it pretty much like you would sprintf, with
the added safety feature that you provide the length of the output buffer so
it doesn't scribble past the end of it:

    g_snprintf(buf, len_buf-1, "%6.4f", myfloat);
