A 32-bit signed integer that is equivalent to the number in value, or 0 (zero) if value is null. A naive solution is to create an array of Integer type and use a regular for-loop to assign values to it from a primitive integer array. You can use the same method to convert an array object to a string data type. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6. value is greater than Int32.MaxValue or less than Int32.MinValue. It takes an array, as a parameter (and also has overloads for Iterable and Iterator parameters) and calls toString() on each element (if it is not null) to get each elements string representation. Making statements based on opinion; back them up with references or personal experience. Returns an object of the specified type whose value is equivalent to the specified object. If you prefer not to handle an exception if the conversion fails, you can call the Int32.TryParse method instead. Now, if we run the code, the result will be like this. Python defines type conversion functions to directly convert one data type to another. There are several ways to convert String to Object, but we will see the most efficient way. any chance you want to save to json to a database or a file: To convert a valid JSON string back, you can use the json_decode() method.
