    Modifier and Type | Method and Description
    --- | ---
    `static int[]` | `factor(int n, int[] fromfactors)` Return the prime factors of n.

  - ### Method Detail

    - #### factor

          public static int[] factor(int n,
                     int[] fromfactors)

      Return the prime factors of n. The method first extracts any factors in fromfactors, in order (which needn't actually be prime). Remaining factors in increasing order follow.

    - #### log2

          public static int log2(int n)

      Return the integer log, base 2, of n, or -1 if n is not an integral power of 2.
