Method Detail

compare

public static int compare(double value1,
                          double value2)

Compares double-precision floating-point numbers applying the default error tolerance.

Parameters:

value1 - First argument to compare.

value2 - Second argument to compare.

Returns:

How the first argument compares to the second:

• -1, smaller;
• 0, equal;
• 1, greater.

compare

public static int compare(double value1,
                          double value2,
                          double epsilon)

Compares double-precision floating-point numbers applying the specified error tolerance.

Parameters:

value1 - First argument to compare.

value2 - Second argument to compare.

epsilon - Relative error tolerance.

Returns:

How the first argument compares to the second:

• -1, smaller;
• 0, equal;
• 1, greater.

compare

public static int compare(byte[] data1,
                          byte[] data2)

Compares big-endian byte arrays.

Parameters:

data1 - First argument to compare.

data2 - Second argument to compare.

Returns:

How the first argument compares to the second:

• -1, smaller;
• 0, equal;
• 1, greater.

increment

public static void increment(byte[] data)

Increments a big-endian byte array.

increment

public static void increment(byte[] data,
                             int position)

Increments a big-endian byte array at the specified position.
