Numeric sorting in Perl - wrong output

Question

I am trying to sort an array, but the output is not as expected. My array has:

After I sort with following code, I get same array:

@sort_start= (sort{my $b <=>my $g} @start);

I cannot understand why.

You should use $a instead of $g, and don't use my in the sort block. Refer to perldoc -f sort:

@sort_start= sort {$b <=> $a} @start;

You should use warnings. That would've shown you some messages.

If you want to sort in ascending order, swap $a and $b.
