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()

   * @param version the version of the applet as a float
   * @throws Exception if it fails to write file
