Can you calculate Pi using a Solver?

RE: Can you calculate Pi using a Solver?
I tried this method on the 32S and worked perfectly. However when I tried it on the 32SII the result is way off. Is the programming that different on both machines?

Following your suggestion, here is a solution of Euler's equation on the HP32S (I like this little machine:-):

LBL E
INPUT X
RCL X
0
CMPLXe^X
1
+
x^2
x<>y
x^2
+
RTN

Then:
FN= E
SOLVE X

The 32S displays "NO ROOT FND" but the best guess 3.14159265359 is in X.

Anyhow, for me it's a complicated way to just solve COS(X)=-1.
