Can someone do a calculation on a TI Inspire CAS?

Hello!

If you are using the sin(pi) on a TI-nspire you get zero.

But I think, the value of 3.1415926534 for pi is not a good choice.
For calculation in real world physics normally you don't need so many significant digits, so I think using pi directly is ok.

And I have tried several calcs:
DM-42: 1.897932384626433832783634455164435e-10
DM-15: 5.9e-10
fx-991DE PLUS: 1.898e-10
HP-300s+: 1.898e-10
numworks: 1.8997932e-10
HP-35s: 1.89793238e-10
2DS: 0
I have input the number from the last post 3.1415926534 (and not 3.141592654) with all digit if possible.
As you can see one digit more, you get a result half as big as the other (-4.102069e-10 by numworks).
So I think rounding to 0 is fine for real world problems.
That's the reason HP choice FIX 4 as default for many calcs.
