I would have liked to re-buy a FX-100. Because of what I would have done at least need, I would have known about me. It exists but not well.
Of course, I bring the computer mathematically with my application scenario is not the limit. For me, therefore, the handling of the computer in their daily business counts more than average.
The key I think still ok. Something spongy from feeling unproblematic in the function.
Compared to many other calculator, the keys are probably a bit bigger - what I find enjoyable. I do not want to focus on the operation of the calculator, but on my real work.
(A desktop computer falls out, because I work in different locations and therefore must carry the number cruncher.)
A pity, I find that the 1000 separator characters are not displayed when entering numbers. The absence reduces the readability of longer numbers.
What I like good, is the hard case. So I need me during transport in a always quite full briefcase worry that slightly damaged. becomes.
For me, new (as long as I have not bought a calculator!) Are the different memory. In the memory E (as) I have, for example, the Umrechenkonstante for DM / laid me. Not that you could not remember the 1.95583. But instead of 7 buttons I now need only 2. Under F (such as land), I laid a project-dependent constant that will be overwritten in the next project. This feature is a real help.
So great the variety of memory: For M I miss a "M" key. Saves de display without further arithmetic operation. Ok, go with Schiff / Store / M. then are just 3 buttons.
Sometimes I also use the function to scroll back in the calculations. Goes faster than - for example, when the suspect entered incorrectly - to be expected again.
I have him now 4 weeks in use and we will certainly be better "used to each other" even discover some useful functions for me and with the help of the instructions. Speaking of the manual.
For me, the letters to the instructions are getting a bit too small. Online can be found under the heading "Instructions fx85" but some sites for the corresponding PDF. And at lower Browse, there are also "personal" guides users with additional tips (the videos you can but give genuine, that is usually only Mi ..).
Why 4 stars?
He is not perfect in my estimation, therefore, it can not be a 5 star.
And he asks me also functions available (several presets, 1000 separator) who support me in my daily work and the case I find very useful for transporting in a full briefcase.
That's why I think he is better than 3 stars (does what it should, but no longer).
I hope my review will help you a little when choosing a suitable computer.
And since very many people buy it for a test: Much success ;-)
