Might be. I've never seen it used that way, though, I know that some people prefer parentheses around the fraction to the right of integers.
I learned at grade/primary school, it's useful as a teaching tool for fractions. Although, I do recall using something similar for partial fractions in college.
That said, even Wolframalpha appears to disagree, which I find mildly funny if what you say is true.
Probably the best list imo. I remember picking Radiata Stories up, at random, for my birthday. It blew me away. The story, combat and recruitment mechanic are different from everything else I experienced at the time.
And a few suggestions also:
Def Jam: Fight for NY. Lowkey my favorite fighting game, with 4-players simultaneously beating the crap of each other.
Battle Stadium D.O.N.. Fighting/smash bros style game with the biggest jump stars at the time (Dragon Ball, One Piece, Naruto).
Dokapon Kingdom. Board/rpg game with a lot of fun mechanics.

In wolfram alpha they call it mixed fraction or number.
