28S Pi Functionality

[Matt Fegenbush]

I have reviewed the manual regarding the pi function on the 28S, but what I would like to do is not have to hit ->NUM every time I evaluate an expression containing pi. Is there a way to configure the approximation instead of the function?

36 CF does what you want. More at section 24 of the Owner's Manual, page 205. HTH.

That did the trick, thank you very much.

One may avoid the need to set the global flag to return numerical values by storing the program << ->NUM>> in a variable named PI.

You can then directly evaluate expressions like for example, '2*PI*5^2' or use the solver with symbolic expressions such as '2*PI*R^2' setting R to 5 and solving for EXPR= to obtain a numerical result.
