206 Spreadsheet

Using the CAS in spreadsheet calculations

You can force a spreadsheet calculation to be performed by the

CAS, thereby ensuring that results are symbolic (and thus exact).

For example, the formula =√Row in row 5 gives

2.2360679775 if not calculated by the CAS, and √5 if it is.

You choose the calculation engine when you are entering the

formula. As soon as you begin entering a formula, the

key changes to or (depending on the last

selection). This is a toggle key. Tap on it to change it from one

to the other.

When is showing, the calculation will be numeric (with

the number of significant digits limited by the precsion of the

calculator). When is showing, the calculation will be

performed by CAS and be exact.

In the example at the right, the

formula in cell A is exaclty the

same as the formula in cell B:

= Row

–√(Row–1). The only

difference is that was

showing (or selected) while the

formula was being entered in

B, thereby forcing the

calculation to be performed by the CAS. Note that CAS

appears in red on the entry line if the cell selected contains a

formula that is being calculated by the CAS.
