28S Pi Functionality



#2

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?


#3

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


#4

That did the trick, thank you very much.

#5

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.
