A Quick Look at the Casio fx-50FH Plus (and quick comparison to the fx-3650p)

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:  ), 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,
