A Quick Look at the Casio fx-50FH Plus (and quick comparison
to the fx-3650p)
Recently I purchased a Casio fx-50FH Plus solar programming
calculator on eBay.  I purchased a used
model in the United States.  The Casio
fx-50FH Plus is a solar programming calculator, that is unfortunately, not available
in stores in the United States.  
The fx-50FH Plus and its variants are H.K.E.A.A. approved,
meaning that they are approved for certain certification exams in Hong Kong.  As far as I could tell from Casio’s worldwide
site, (link:  http://www.casio-intl.com/asia-mea/en/calc/scientific/programmable/fx50fh/?m_no=166
 ), the variants are the same.  
I really like these solar programming calculators from Casio
and wish they did sell here in the U.S.  I
am also really like the screen on the fx-50FH Plus: the text on both lines are
BIG! (see the picture above)
The Basics
It is a two line calculator (no math print) that allows up
to four programs.  What is an outstanding
feature of the fx-50FH is its library of 40 constants and 23 built in formulas.  The fx-50FH also has the standard base
conversions and operations (DEC, BIN, OCT, HEX), complex number arithmetic, seven
memory registers (A,B,C,D,X,Y,M), and fractions. 
The fx-50FH vs. the fx-3650P
So what are the differences?

Calculus:  The
fx-3650p has a numerical integration function while the fx-50FH doesn’t.  
Statistics:  Both have
the following regression models: Linear, Logarithmic, Power, Inverse, and
Quadratic.  The fx-50FH has two types of
exponential:  e  (y = a*e^(b*x)) and ab (y = a*b^x).  The fx-3650p has the ab type.  
Programming:  The
fx-50FH Plus has 680 program steps allocated to as many as four program areas,
opposed to the 360 for the fx-3650p. 
Only the fx-50FH has the If-Then-Else-IfEnd structure, While-WhileEnd
structure, and the For-To-Step-Next structures. 
Powerful stuff for a programmable non-graphing calculator (like the
Casio fx-5800p).
At first site, I am impressed and am looking forward to
playing with the fx-50FH in the future. 
If am not mistaken, the fx-50FH Plus an updated of the fx-50F.  (a 680 byte memory is a big step up from just
29 for the 1987 original).
Until next time,
Eddie
