- * E.g. a value of 3000000 would be converted to "3 us", 20000 to "50 ms".
+ * The period is specified as a rational number's numerator and denominator.

- * @param frequency The frequency in Hz.

- * @return A newly allocated string representation of the frequency value,
+ * @param v_p The period numerator.
+ * @param v_q The period denominator.
