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.
