Examples of java.io.DataOutputStream.writeFloat()

java.io.DataOutputStream.writeFloat()
Writes a 32-bit float to this output stream. The resulting output is the 4 bytes resulting from calling Float.floatToIntBits(). @param val the float to be written. @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readFloat()

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        outputStream = new DataOutputStream(baos);
        try {
            outputStream.writeUTF(location);
            outputStream.writeFloat(latitude);
            outputStream.writeFloat(longitude); 
            outputStream.writeByte(timeZoneSrc);
            outputStream.writeShort(timeZoneMin)  ;
            outputStream.writeBoolean(isDSTOn);
            outputStream.writeShort(altitude);
            outputStream.writeShort(temperature);
