⭐ in reply to How do I round a number?

Different rounding schema:

# 1.1 => 1;  1.9 => 1;  -1.1 => -2;  -1.9 => -2
$rounded = POSIX::floor($value);

# 1.1 => 2;  1.9 => 2;  -1.1 => -1;  -1.9 => -1
$rounded = POSIX::ceil($value);

# 1.1 => 1;  1.9 => 2;  -1.1 => -1;  -1.9 => -2
$rounded = round($value);
sub round {
  $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5)
}
