Description
Reads and returns an Extended floating-point number from the reader object's stream.
ReadFloat is a helper method used by other reader methods to read an Extended floating-point value at the current reader Position.
ReadFloat calls ReadValue to check whether the value-type indicator is vaExtended,and then ReadFloat calls Read and returns the retrieved Extended value. Otherwise, ReadFloat returns the stream position back before the value-type indicator, calls ReadDouble, and returns the retrieved value.
ReadFloat advances the reader Position after the last byte it has read.
