maxNum

public static int maxNum(int a,
                         int b,
                         int c,
                         int d)

Compares the absolute values of 4 signed integers and returns the unsigned magnitude of the number with the greatest absolute value.

minBits

public static int minBits(int number,
                          int bits)

Calculates the minimum number of bits necessary to represent the given number. The number should be given in its unsigned form with the starting bits equal to 1 if it is signed. Repeatedly compares number to another unsigned int called x. x is initialized to 1. The value of x is shifted left i times until x is greater than number. Now i is equal to the number of bits the UNSIGNED value of number needs. The signed value will need one more bit for the sign so i+1 is returned if the number is signed, and i is returned if the number is unsigned.

Parameters:

number - the number to compute the size of

bits - 1 if number is signed, 0 if unsigned

writeAt

public void writeAt(int offset,
                    byte[] b)
