On a side note, if the digits repeat, then the number is rational (it can be expressed as a ratio of two integers). We can find that fraction as follows:
Let x = 143.064646464….
1. 10x = 1430.646464….
2. 1000x = 143064.64646464….
eq 2 - eq 1 gives:
990x = 143064 - 1430
990x = 141634
x = 141634/990 = <<< exact value
