Re^4: Floating point number counting script stuck in a loop

Huh, I wonder why the tutorial uses (), then? Do they have any purpose or does it just make things look nice, what with all the rounded-off ends? XD

Thanks for that, by the way, I've always wanted to be able to compress scripts to be painfully tiny. (No sarcasm, it really does look impressive).

I did read that variables can be put in strings and I had it that way at the beginning, but I thought it might have been the problem and never changed it back after I tested that.

Thanks for the help.

Tinyish (but most on perlmonks can do better than I): `#!/usr/bin/perl -w use strict; for (1..9) { print $_/10, "\n"; }` [download] Does the same as the question asks - likely wouldn't have accomplished the aim of the exercise, which was probably to teach you about using == with floats, but well ;) See perlvar for explanation of $_	[reply] [d/l]

`print "0.$_\n" for 1 .. 9;` [download] ;) Perl is environmentally friendly - it saves trees	[reply] [d/l]

Then you might like: `#!/user/bin/perl -w use strict; use warnings; print "@{[$_/10]}\n" for 0 .. 9; print "End!\n";` [download] Perl is environmentally friendly - it saves trees	[reply] [d/l]
