hi
there is not math subforum or homework help i guess
on some webpage i hve found formula how to count frw speed - velocity of skill burst of speed of assassin of diablo 2 game
this is it:

but i dont know what mathematical operation is that ",70" ?
i'm from europe and here if you want write number for example: one and half, it will be 1,5
but in usa, they write 1.5
but still cant figure what is that ,70
also between "min" and first bracked is nothing. i understand it is hidden "*" - multiply ?
