Let's say there is this array of arrays:

```
theArray = [["name1", 12.23423, 54.243, 6.23566, 5675.552, ...],
            ["name2", 345.8655, 92.9316, ..],
            ["name3", 99.56756, 52.988, 3.09889, ...],
            ...
            ];

```

Each sub-array starts with a string and it is followed by numbers. My aim is to reduce the numbers to a shorter form.

I know that this can be done using `.toFixed(2)` in order to have only two digits after the dot by I don't know how to access them because of the string in the front.

I want them to remain as numbers because I must use them as data for a chart.

Do you have any suggestions?
