28S Pi Functionality « Next Oldest | Next Newest »

 ▼ Matt Fegenbush Unregistered Posts: 20 Threads: 3 Joined: Sep 2011 10-16-2012, 11:22 AM 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? ▼ Gerson W. Barbosa Unregistered Posts: 2,761 Threads: 100 Joined: Jul 2005 10-16-2012, 12:01 PM 36 CF does what you want.

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.
