**Review: Casio fx-260 Solar II (fx-82 Solar II)**

Company: Casio

Year: 2017

Type: Scientific

Power: Solar

Statistics: 1
Variable

Operating
System: AOS (classic)

Cost: $8.99

**So New?**

Ironically, I
was not able to find the fx-260 Solar II online, but saw it on a very rare trip
to WalMart. The Casio fx-260 Solar II calculator
is so new that still isn’t featured on the Casio’s website (as of
3/27/2017).

As a note: The fx-260 is the name for the version sold
in the United States. Internationally,
the calculator is known as the fx-82 Solar II, and Casio

*does*have that calculator on its website:**An Update of a Classic**

The fx-260
Solar II is an update of the very classic (and still selling) Casio fx-260
Solar (outside the United States, it’s the fx-82 Solar). Functionally, the fx-260 Solar II is the same
as the classic fx-260. As a reminder:

* Trigonometric
functions

* Angle
conversions: polar, rectangular, to degrees (Shift Mode 4), to radians (Shift
Mode 5), and to grads (Shift Mode 6)

* Random
numbers

* Logarithms
and exponents

* 1 Variable
Statistics

* Fractions (up
to a maximum of 10 digits between the whole, numerator, and denominator parts)

* DMS/Decimal
math and conversions

Pretty handy
for a basic scientific calculator. The
fx-260 Solar II, like its predecessor runs entirely on solar and light power,
hence a completely green calculator. 50
lux is required.

There is a NF
version which was stated on the quick manual that came with the fx-260 Solar
II. The NF stands for “no fraction” and
the diagram shows the fraction button [ a b/c ] button disabled.

The percent key
still works the same as the predecessor.
The keystrokes:

Find N% of
W: W [ * ] N [Shift] [ = ] (%)

W is N% of the
whole: W [ ÷ ] N [Shift] [ = ] (%)

Markup/Tax: W [ * ] N [Shift] [ = ] (%) [ + ]

Discount: W [ * ] N [Shift] [ = ] (%) [ - ]

The differences
between the fx-260 Solar II are:

1. The processor is faster, most noticeable when
try to calculator n! when 50 < n <
69. In reality, it can be seen as negligible
since the predecessor is no slow poke.

2. The fx-260 Solar II is has a more compact
design than the original fx-260 Solar. The
fx-260 Solar II is close to a size of an iPod Touch/iPhone. Per the manual, the dimensions of the fx-260
Solar II are 3/8” height, 2 3/4” width, and 4 3/4” depth.

3. The one difference I’m not a fan of is how
the mode reminders are moved to the back of the calculator. Furthermore, the reminders are white text on
a white background. It is only because of
the etching that the reminders could be readable.

Easter egg: I
think this is the first time Casio dated their manual (2017).

**Final Verdict**

If you are fan
of small calculators, solar calculators, Casio, basic level scientific
calculators, or just want something nice to add to your collection, then the
fx-260 Solar II (and the original fx-260 Solar) is a nice pick up for not much
money.

Can I use this in place of TI-83 or 84 plus?

ReplyDeleteOnly if you don't need/want a graphing calculator.

Deletecan you type negatives and if so how

DeleteTo type negative numbers, press the change sign key [+/-] after you enter the number. Example: -20 is achieved by pressing [ 2 ], [ 0 ], [ +/- ]

ReplyDeleteIs this calculator allowed on the Algebra 2 EOC? I'm guessing it is since the fx-260 is allowed, and the fx-260 II is basically the same thing, but I need a definite answer, so I know buying it wasn't a waste of money.

ReplyDeleteIt nice ! Thank for sharing .

Great review Eddie. I too just saw this by accident at Walmart for $7, as they often go on sale after school and get expensive just before school starts. So if you want want, now is the time.

ReplyDeleteSome added review items worth mentioning:

Overall improvement in ergonomics from a calculator already unique for its ergonomics: sensitive enough to work in artificial light alone without batteries, good tactile feel, just the right functions available, fast response, small and light, durable make, my older ones still look new and are over 10 years old

The new design is inspired by the FX-991EX in the mettalic like finish to the top of the calculator, the white cover and body, the sculpted key and color BLUE for RED on AC and C.

Its physically smaller and lighter but its generally as if you took out MODE labels and shortened it accordingly. It fits even better now in a shirt pocket during lab runs.

The LCD is far more reflective on mine, and I bought two, with marked improvement in contrast.

The case is much shorter travel, so it only takes a small thumb swipe and its out, the flip it on its back, and slip back into the case takes a lot less movement than the older one.

The FX260 has been my general purpose scientific calculator for over 18 years since its inception, as my workhorse calculators. They are so cheap I have about 6 scattered throughout my offices, labs and workbags. I never expected it ever to be updates but there it is!

Could you do me a favor. Test the new one “355 [a b/c] 226 [tan]” on RAD mode, then see what you got.

Delete(355/226 is close to pi/2, 355/226 = 1.57079646, where pi/2 = 1.570796327)

Eddie

Thx, Eddie, It's the same with the old one (-7497938.067). The precision of new model was not improved, even the same with more older model, like fx-82SX, fx-250HA, fx-350HB, fx-65...

DeleteIs this a programmable calculator?

ReplyDeleteNo.

DeleteHelp. I seem unable to enter negative data in statistics mode. Can you offer any help?

ReplyDeleteHi,

ReplyDeleteI have a question: is there any solar powered calculator which can store programmed function in memory? (I wish to have programmable calculator with solar power) :)

I like programmable calculators powered by solar power. The two that are currently sold are the Casio fx-3650P and the Casio fx-50F II. Unfortunately, those two calculators are not sold in office stores in the United States, so you will need to use eBay or another online site. Both models have 4 program areas, the fx-3650P has 360 bytes while the fx-50F II has 680 bytes and an extended programming language. The fx-3650P has numerical derivatives and integrals, while the fx-50F II has 23 built in formulas.

DeleteVery nice review. One question though is version II keys are rubber buttons like the previous model?

ReplyDeleteYes.

DeleteNice Post....

Casio has always dated their manuals. The date ( year and month) appear after the letters SA. For example in your manual SA16-11 means revision year 2016, month 11 (this is the first release). On my fx-991ES Plus manual, it says SA09-07A, which means revision year 2009 month 7 (The calculator was released in 2008).

ReplyDeleteIs there a digital version of this calculator available?
