Question

I am trying to round the values in my array to 2 decimal points. I understand i can use math.round but will that work for an whole array? Or will i need to write a function to round each value individually.

Answer 1

Loops!

var x = 0;
var len = my_array.length
while(x < len){ 
    my_array[x] = my_array[x].toFixed(2); 
    x++
}

And, yes, a while loop is faster here.
