Example String parse 001

 

 

Description

This example shows how a String may be parsed, using the builtin LISP parsing rules. Each of the examples is parsed and converted, except the last example. It cannot be recognized, and the original String is returned.

 

Details

The parse function converts the String "3.141592" into the Number 3.141592.

(parse "3.141592") Returns: 3.141592

The parse function converts the String "#Jan,19,1993" into the Date #Jan,19,1993.

(parse "#Jan,19,1993") Returns: #Jan,19,1993

The parse function converts the String "#(1 2 3)" into a Vector.

(parse "#(1 2 3)") Returns: #<Vector 2194>

The parse function cannot recognize the type of 23Hello so the original String is returned.

(parse "23Hello") Returns: 23Hello

Notes and Hints

The parse function removes the double-quotes(") before and after the String determines the data type of parsed value.
