Public Sub Button1_Click()

  Dim i As Integer
  Dim arr As Float[][]= [[1.11111, 2.23456], [2.27654, 3.3], [3.4,
4.50], [123456.789, 987654.321]]

  For i = 0 To arr.Max
    Print Round(arr[i][0], -2), Round(arr[i][1], -2)
  Next

End

Apart from Round(float,int) accepting a -ve number which is well
explained in the help, I would have thought the rest was intuitively
obvious to even the most casual of observer :-)

I've said this before and no doubt I'll say it again, the gambas help is
very succinct.  Read every word in a help page and consider what it
means.
