Method Detail

getIEEEDouble

public static double getIEEEDouble(byte[] data,
                                   int pos)

Gets the IEEE value from the byte array passed in

Parameters:

pos - the position in the data block which contains the double value

data - the data block containing the raw bytes

Returns:

the double value converted from the raw data

getIEEEBytes

public static void getIEEEBytes(double d,
                                byte[] target,
                                int pos)

Puts the IEEE representation of the double provided into the array at the designated position

Parameters:

target - the data block into which the binary representation is to be placed

pos - the position in target in which to place the bytes

d - the double value to convert to raw bytes
