You need a percentage to be rounded not to 0/100 but a more accurate value. For instance, given

```
var n = 0.76,
r = Math.round(n);
```

r will be 1 since it is closer to 1 than 0. If we want to have smaller round values, like 0.05 increments, we will need to use a mask and modify the formula a bit:

```
var n = 0.76,
mask = 0.05,
r = mask * Math.round( n / mask);
```

r will be 0.75 now. The obvious step if we want the final percentage, we multiply by 100 factor and add the symbol:

```
var n = 0.76,
mask = 0.05,
r = 100 * mask * Math.round( n / mask) + "%";
```

r will be 75% now.
