How to store values ​with decimal places?

Question

I need to calculate values ​​for percentage and I need them to have two decimal places and the minimum value is 0.00 and the maximum value is 100.00.

When I use some decimal place, for example: 80.01 the compiler complains saying that I have to change to ufixed, but I saw that it is not supported.

What is the correct way to approach this contract?

CONTRACT

struct Vote {
    uint total;
    uint totalPercentage;
}
Vote private _abstentionVotes;
uint private _totalElectoresVoted;
constructor() {
        _abstentionVotes.total = 0;
        _abstentionVotes.totalPercentage = 0.00;
        _totalElectoresVoted = 0;
}
function _calculePercentageOfVote(uint totalVotes) private view returns (uint) {
    return ((totalVotes / _totalElectoresVoted) * 100);
}

Answer 1

You can take a look at a workaround for calculations using decimal numbers:

Answer 2

A workaround might be multiplying by 10^n and returning this result. In the application you can divide it by / 10^n.
