RE: Sharp EL-W506T vs. Sharp EL-W516T
My daughter had to buy an EL-W506X for her math course at school. This is essentially a W506T without WriteView. When she allowed me to play with it I tried one of my standard tests, the definite integral int(0, 6, exp(x^3),x). The result came up quite fast but was way off (the fx-991DE is dead on btw.).
I was curious about the algorithm they implemented and found, they use Simpson's formula but would never calculate more than n=100 intervals. No matter the precision needed or fixed digits.
This makes it rather unreliable when used for integrals.
