[BUG] Incorrect value while precision greater than 7

I am getting an unexpected result both toFixed() and formatMoney() output

## toFixed
```
toFixed(0, 10);
```
Output:
```
0.0000000100
```

Expected:

```
 0.0000000000
```
## formatMoney
```
formatMoney(123.1234567890, { symbol: '',  decimal: '.', precision: 8 })
```
Output:
```
123.12345680
```

Expected:

```
 123.12345679
```

Any idea?
