This Galaxy 40 sold in Belgium, France and Italy is a slightly modified version of the Galaxy 40x sold elsewhere. 

The only difference between this two calculators is the behavior in calculations with fractions. While the Galaxy 40x accepts the input of "units" with the u key the Galaxy 40 works with real fractions only. 

Galaxy 40 (French fractions):

2.5 D-F 25/10

Galaxy 40x (German fractions):

2.5 D-F 2 u 5/10

Texas Instruments continued its calculator line supporting "French fractions" and introduced in 1997 the TI-40 Collège

If you are interested in the self-test procedure of the Galaxy 40 calculators you should read Koen's article here.

Don't miss the innovative Casio AL-8 calculators introduced in 1975 and already operating and displaying fractions and the TI-Primaire Plus introduced in 2014.
