I’m not really sure what you mean by your question, as numbers are actually infinite.

The percentage notation is mostly there for readability, as two digits of precision is a good balance between enough details and not too much details. It also serves to express that your are discussing an amount in proportion of some other amount, instead as in absolute.

For example, “the amount I have is 0.5 times the amount I need” is shortened as “I have 50% of the amount I need”. Both mean the exact same thing, using percentage is a specific wording so can be more concise.
