Hello all!

Just joined because I'm going through integration and was checking my answers on my new fx-991EX.

I input the following: 10x(x^(1/2)-2) between 0 and 4 (with the integration button, of course).

The first weird thing was that it took far longer than it usually takes, and secondly, the answer it gives is: -32.00000017 when doing it by hand the answer is simply -32.

I downloaded the emulator for this calc and it gives the same answer. I tried both degrees and radians with the same result.

I'm mostly just curious why this happens if anybody knows.

Thank you!
