**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.
