Re^3: IF condition with a range

You're thinking of something like this:

if ( it is equal ) {
   do something;
}
elsif ( it is equal or close ) {
   do something else;
}
[download]

But you want:

if ( it is equal ) {
   do something;
}

if ( it is equal or close ) {
   do something else;
}
[download]

Or even:

if ( it is equal or close ) {
   if ( it is equal ) {
      do something;
   }

   do something else;
}

Aha, so you mean I should have only ifs and not if-elseif. Good, I will try that!	[reply]

Aha, so you mean I should have only ifs and not if-elseif. Note that there is a potential pitfall of `if (...) {...} if (...) {...}` instead of `if (...) { if (...) { ... } ... }` - it's easy to make a mistake with the logic: `if ( /^[brc]at$/ ) { # match "bat", "rat", or "cat" print "It's an animal\n"; if ( /^b/ ) { print "... and it flies!\n"; } }` [download] This is not the same as: `if ( /^[brc]at$/ ) { print "It's an animal\n"; } if ( /^b/ ) { print "... and it flies!\n"; }` [download] Because the latter will match any word that starts with `b`. Of course, in this case, it seems obvious that if the numbers are equal, they will also be within +/- 1 of each other, but mistakes like the above can happen if you don't think the logic through (and test it!). Update: For example, consider the special case of `Inf` that syphilis suggested, which I've now added as a test case to my other post.	[reply] [d/l] [select]
