Digital camera reviews of Casio FX-115MS Plus Scientific Calculator
Digital camera Review: Cassio vs. Sharp
Summary: 5 Stars
I have purchased within the last two weeks both the Casio fx-115MS and the Sharp EL-506VB calculators. If you enter (21)2 in both calculators and then press the equal key, the Casio will display "Syntax Error" and the Sharp will display "Error 1.". Why is an error message displayed in both calculators? Does this mean that there is the same "bug" in both calculators?On the other hand, if you enter 2(21) in both calculators and then press the equal key, both calculators will generate 42 in their respective display areas. It must be that each calculator's design is such that both do not recognize an "operator" (addition, subtraction, multiplication, or division) when a number enclosed in parentheses is immediately followed by another number.
If you enter (21)2, both calculators recognize it as an error in "syntax" or rules by which either unit can calculate or perform an "operation." You did not enter an operator so the calculator cannot perform any calculation. In the first case, (21)2, no operation (multiplication) is recognized by either calculator and as a result, both units generate the "error" message. In the second case, 2(21), both calculators recognize the "operator" (multiplication) and performs the operation to arrive at the correct answer, 42.
Nevertheless, both the Sharp and the Casio recognizes the "order of operation." For example, if you enter the expression (2 +3)2 and then press the equal key, you will again see the "error" message displayed by both calculators. However, if you enter (2 + 3) x 2, you will see the correct answer displayed by both calculators, that is, 10. It is evident that any number or expression enclosed in parentheses as the first entry which is then followed by a number will generate the "error" message.
I just tried entering (2 + 3)2 on the scientific calculator that comes with Windows XP Home edition. When I pressed the enter key, the display remained at "2." This means that the computer did not recognize any "operator" after (2 + 3). If you enter "(" then "2" then "+" then "3" then ")", you see immediately that the result of the operation is 5. Go on and enter "2" and press the equal key, and you see that nothing happens because you did not enter any operator (multiplication) after 5. You are stuck at 2. While the calculator in Windows will not generate an "error" message on the one hand, both the Sharp and Casio will to let you know that you have violated the "syntax" or rules used by either calculator. Remember, a calculator is just a dumb paper weight and it won't do anything for you until you tell it exactly what to do. However, both the Sharp and Casio will perform various calculations for you but will only follow the "syntax" or rules incorporated in their respective designs.
One feature on the Sharp that I really like is the fact that each numeral or expression you enter is displayed in the lower line of the two line display before you enter an operator. This allows you to see and make sure you are entering the correct data. Once you enter the correct data and follow it with some type of operator, the data you entered appears on the upper line of the display area. This allows you to "double check" all entries before you press an operator or equal key. The Casio fx-115MS on the other hand shows all data entered on the upper line first just as you enter it in the calculator.
I like both calculators equally well, and both have their advantages and disadvantages. But the advantages and disadvantages spring mostly from user preference. For me though, the Sharp EL-506VB has the edge because it comes with more thorough and user friendly documentation explaining each function more thoroughly than the Casio fx-115MS. So for five dollars more the Sharp is worth it.
The ... Casio graphing calculator also looks like a good investment and seems to come with a very adequate booklet of about 150 to 200 pages. That will most likely be my next calculator.
Digital camera Review: Engineer
Summary: 3 Stars
Well I am a big Casio fan, having bought fx's for years, not to mention the 30 year old watch that continues to work perfectly to this day..... however, while it's a nice calculator, I bought it off Amazon because it had base conversions, something we use a lot in programing... imagine my surprise when I discovered that the binary conversion of 512 overflowed the registers. This is a very small number, not even 10 bits worth, which makes it useless
The limitation was in the instructions... but not on the package or Amazon ad. That said, it's a great, easy to use advanced calculator, but it doesn't do me any good in the area I specifically bought it for. Still looking for now. Bound to be a casio somewhere
If you need binary/hex/decimal conversion, look elsewhere.
Digital camera Review: Engineering Student's Best Companion
Summary: 5 Stars
I think this calculator is great for both high school and college students, because it has virtually everything a student needs out of a calculator...low-cost, reliability, durability, long list of functions, standard features and more...I think even professional engineers might appreciate this calculator...Within it's price range, I think it's the best one out there.Digital camera Review: Everyone is jealous
Summary: 5 Stars
Everyone gets jealous when they see my FX-115MS with S-VPAM. Even the TI-89 jockeys get red in the face. This little math machine can do anything except graph with the same computational power as some of the big-boys at 1/10th the cost. Best calculator I've owned, hands down. Blows anything in the same price range by TI, Sharp, or any others right out of the water. I'm always finding new helpful functions as I take higher level math courses, it hasn't left me stranded ever.
Good for chemistry, AP chemistry, geometry, precalc, calc, physics... I've had this little computer since freshman year of high school... Now I'm a freshman in college. I don't see anything else replacing it, except maybe the newest in the FX-*MS line, even in graduate school.
Digital camera Review: Excellent Calculator
Summary: 5 Stars
I've been using a Casio that I bought from the 90's. I decided to upgrade and I was nicely surprised on the features. The two line makes it easy to see if you entered a problem wrong. There are buttons with kilo and milli units so you can hit 5k to enter 5 kilos. The calculator can also integrate and do defferential calculations but it does take a minute sometimes. The only setback is that the instructions that came with the calculator are poor.
