Only 553 functions. We Latin Americans are not good enough at math to deserve the extra ~140 functions in the German version, it seems.

RE: CASIO CLASSWIZ fx-991SP X Iberia
Hi,

I am calculator collector from singapore. I am interested in obtaining the following:

1. FX-991SP X Iberia (NOT FX-991SP X II Iberia)
2. FX-991LA X
3. FX-991LA PLUS

was wondering if anyone from this site able to help me?

Regards.

Did not know there were so many versions of the fx-991EX Classwiz. Like Latin America, it looks like the United States got a stripped down version as well at 552 functions. No GCD, LCM, Int, Intg functions nor a periodic table.

Hi all,

fx-570SP X Iberia here, which is the non-solar fx-991SP X Iberia.

Self test 1 shows "CY-254 VerA".
This one has also translated keys for the trigonometric functions (SEN and ARCSEN instead of SIN and SIN-1).

This model don't have DECIMAL-POINT IS COMMA Wink

The German fx-991DE X seem to have many more unit conversions compared to the "international" EX model. It has 14 extra (26) length conversions, 12 extra (14) area conversions, 16 extra (20) volume conversions, 2 angle conversions ("rad -> r" and "r -> rad" - I don't know what those are!), 8 extra (12) mass conversions, 8 time conversions, 6 speed conversions, 2 acceleration conversions ("Gal -> m/s^2" and "m/s^2 -> Gal" - whatever Gal means!), 2 torque conversions, 6 force conversions, 10 extra (18) pressure conversions, 12 extra (16) energy conversions, 2 heat flow conversions ("Btu/min -> W" and "W -> Btu/min" - I guess these can be considered as 2 extra power conversions, but they are in a separate submenu), 2 specific heat capacity conversions, 2 viscosity conversions, 2 kinematic viscosity conversions, 8 magnetism-related conversions, 4 light-related conversions, and 8 radioactivity-related conversions.

From Wikipedia:

"The gal (symbol: Gal), sometimes called galileo after Galileo Galilei, is a unit of acceleration used extensively in the science of gravimetry. The gal is defined as 1 centimeter per second squared (1 cm/s2). The milligal (mGal) and microgal (µGal) refer respectively to one thousandth and one millionth of a gal."

I sure never knew that! Gentle evidence once again that one can learn something new every day here at MoHPC.

For what it is worth, the fx-991EX RevF is made in Thailand, not China.

RE: CASIO CLASSWIZ fx-991SP X Iberia
Wonder how many models allow solve for d/dx to equal 0 to find a min or max and integrals. The Japanese model, with all of it's extra functions and conversions does not allow this, while the "stripped down" U.S. version allows this in solve. I like having this solve capability over the extra functions/conversions...
