Examples of java.io.DataOutputStream.writeDouble()

java.io.DataOutputStream.writeDouble()
Writes a 64-bit double to this output stream. The resulting output is the 8 bytes resulting from calling Double.doubleToLongBits(). @param val the double to be written. @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readDouble()
