the function frac(x) has a different definition in France than in the (probably!) rest of the world.

Unfortunately it’s another exemple where there is not a universal consensus on the definition of a mathematical notion, and it’s not specific to France.

From Wolfram Mathworld:
Quote: Although Spanier and Oldham (1987) use the same definition as the Wolfram Language, they mention the formula only very briefly and then say it will not be used further. Graham et al. (1994, p. 70), and perhaps most other mathematicians, use the different definition

\( frac(x)= x - \left \lfloor x\right \rfloor \)
