Here is the current kernel code:

#define TQ_MAX_VALUE 255
[snip]
    /* kernel has no printf-support for %f? it'd be better
     * to return this in float. */
    int_part = TQ_MAX_VALUE / entry->quality;
    frac_part = (1000 * TQ_MAX_VALUE / entry->quality) -
            (int_part * 1000);
[snip]
            seq_printf(seq,
                       "\t\"%s\" -> \"%s\" [label=\"%d.%d\"]\n",
                       from, to, int_part, frac_part);
