float. The bit offset within the stream is reset to zero before the read occurs. @return a float value from the stream. @exception java.io.EOFException if the stream reaches the end beforereading all the bytes. @exception IOException if an I/O error occurs. @see #getByteOrder
SQLInputImpl object as a float in the Java programming language. This method does not perform type-safe checking to determine if the returned type is the expected type; this responsibility is delegated to the UDT mapping as defined by a SQLData implementation.

DataInput
float from this file. This method reads an int value as if by the readInt method and then converts that int to a float using the intBitsToFloat method in class Float. This method blocks until the four bytes are read, the end of the stream is detected, or an exception is thrown.
@return the next four bytes of this file, interpreted as afloat.
@throws EOFException if this file reaches the end before readingfour bytes.
@throws IOException if an I/O error occurs.
