RE: Yes, calculators are made from plastic ^^
After reading in one of the previous posts about Kinpo I found this "Calculator forensics" website pretty interesting.
I did the calculation on my calculators: Casio fx-991DE+ (same result as the ES+): 9.000 000 007 333 38 Casio fx-991MS: 8.999 998 637 04 Sharp EL-W506: 9.000 000 015 012 4 TI NSpire CAS (approx): 8.999 999 981 769 1 HP Prime (Home Mode): 8.999 998 642 67 HP Prime (CAS Mode, approx): 9.000 000 005 914 387 202 210 498 285 469(...?) Maybe you can do the same on the HP300s+. If its the same result as for the 991DE+, then this coul be a hint that they are made by the same manufacturer (Or that the developers learned the CORDIC algorithm from the same professor ;-) ) Good to know that the HP doesn't have the problems with the slowliness of the entry. So then I would say the HP300s+ and the Sharp EL-W506 are the best 15...20$ scientific calculators out there. Too bad that the HP doesn't have these user programmable keys like the Sharp does. I really love this feature. But therefore it has gcd, lcm and prime factoring functions. I wonder whether there will ever be "the perfect calculator"? :-D Can't be that hard, right? |
