  • You can specify the storage location in list memory for a calculation result produced by a list 

calculation whose result is stored in ListAns memory. For example, specifying “ 

ΔList 1  →  List 

2” will store the result of  

ΔList 1 in List 2. 

  • The number of cells in the new  

ΔList is one less than the number of cells in the original list.

  • An error occurs if you execute  

ΔList for a list that has no data or only one data item.

 

 

  You can perform arithmetic calculations using two lists or one list and a numeric value.

 

 
  

  Calculation results are stored in 
ListAns Memory.

 

 

k Error Messages

  •  A calculation involving two lists performs the operation between corresponding cells. 

Because of this, an error occurs if the two lists do not have the same number of values 
(which means they have different “dimensions”).

  •  An error occurs whenever an operation involving any two cells generates a mathematical 

error.
