I thought OP was joking but was surprise this kind of dice really exist.
If I can also ask one question here, what's the difference between the 2? like their advantage and disadvantage. ?
I would appreciate if you find my post relevant to the topic.
there is absolutely no difference between rolling 1, 2, 3,... and rolling 0.1, 0.2, 0.3,... as long as the number of possibilities are the same and the house edge is the same and the calculations are the same (no bug like rounding,...). it is like rolling two actual dices one with dots on it (1 dot=1, 2dots=2,...) or write actual numbers on it (1, 2, 3....6) the result is the same.
i also think what veleten said above is false. the multiplier (like 100x) depends on how much the dice site is flexible on letting its users have a chance of winning big. otherwise you can give the same multipliers on any value range. for example in freebitco.in you can roll whole numbers (from 0 to10000) and the multiplier goes as high as 4750
