Description
Reads the next JSON token and interprets it as a Double value.
Instead of Read, you may alternatively use a different reading method if you can anticipate the type of the next token.
ReadAsDouble function reads the next token and returns a Double value. ReadAsDouble calls ReadAsDoubleInternal.
If the token cannot be interpreted as the expected type, an exception raises and provides the path to the token, the number of the line and the position within that line.
