I checked and yes, it is an EL-W506X and it says WriteView right over the LCD.

Let me come back to its calculus capabilities. I repeated the integral and these are the numbers:
Casio fx-991DE: 5.963938092E+91
Prime (Handheld): 5.96393809188E+91
Sharp W506X: 7.466216848E+91

Meanwhile I learned you may specify n as an option when entering the formula.

But does its auto mode of only 100 Simpson intervals really affect everyday calculations? Let us assume some average physics teacher in high school proposing this task: Calculate the energy needed to bring Tesla's starman (1000 kg) one light year away from Earth!
Instead of finding the antiderivative you try to solve the integral(rE, 1 ly, G*mE*1000kg/r^2) numerically. In auto mode without specifying n you will then find (kg*m^2/s^2):
Casio fx-991DE: 6.251161691E+13
Prime (Handheld): 6.25116169124E+13
Sharp W506X: 1.547252475E+20
