The code
if ( $variable > -10 and $variable < 10 ) {
# do something
}
Will not catch -10 itself or 10, so this is really like saying from -9
to 9.
If you want to include -10 and 10, use this
if ( $variable >= -10 and $variable <= 10 ) {
# do something
}
But yeah, it looks like this code always executes the statement anyways.

Hi,
The following if checks for variable between -10 and 10.
if ( $variable > -10 and $variable < 10 ) {
# do something
}
The example you gave looks like it always executes though, so maybe I'm
missing something.
