Description
Reads and returns a Single floating-point number from the reader object's stream.
ReadSingle is a helper method used by other reader methods to read a Single floating-point value at the current reader Position. (Single corresponds to float in C++.)
ReadSingle calls ReadValue to check whether the value-type indicator is vaSingle, and then ReadSingle calls Read and returns the retrieved Single type value. Otherwise ReadSingle returns the stream position back before the value-type indicator, calls ReadInt64, and returns the retrieved value.
ReadSingle advances the reader Position after the last byte it has read.
