Hi there,

I am trying to round to 10 or 100 for particular values

so the following numbers
530
570
2330
2590
3630
3660

would become
500
600
2300
2600
3600
3700

any clues how to do this well?

The classical method uses sprintf, as in the code snippet below.

foreach (qw/530 570 2330 2590 3630 3660/) {
  my $round = sprintf "%.0f00", $_/100;
  print "$round\n";
}

**OUTPUT**

500
600
2300
2600
3600
3700
