minimum expectation of min?

larard has asked for the wisdom of the Perl Monks concerning the following question:

I was wondering about the following behaviour, and couldn't explain it.

$ perl -w -e 'use List::Util qw(min);
@a = (-10...5); 
print "@a\n",(min @a),"\n";'
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5
0

doesn't produce an answer that ties with this

$ perl -w -e 'use List::Util qw(min);
@a = (-10...-5);
print "@a\n",min(@a);'
-10 -9 -8 -7 -6 -5
-10

So why does 'min' in the first example return 0? Just Fixed the code I posted, buggy terminal I was copying from. Sorry.

I tried using Perl 5.8.0, List::Util 1.14 on RH 9 and it worked as expected. I did notice that the code you posted doesn't compile. Try the following: `use strict; use warnings; use List::Util qw( min ); + print List::Util->VERSION, $/; + my @a = (-10...5); print "@a -> ",(min @a),"\n"; ---- 1.14 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 -> -10` [download] ------ We are the carpenters and bricklayers of the Information Age.

Hmmn,your code gives me... `1.09 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 -> 0` [download] looks like it is time to perl -MCPAN -e shell .... thanks	[reply] [d/l]

I get 0 and -10 on Perl 5.8.0 List::Util 1.11, on OS X, but the correct -10, -10 on Perl 5.8.4, List::Util 1.13. Looks like it was fixed between 1.11 and 1.13.	[reply]

I get -10 in both cases. BTW, I presume there were some cut+paste errors in the above. Dave.	[reply]
