Returns the natural logarithm (base e) of EXPR. If EXPR is omitted, returns the log of
$_. To get the log of another base, use basic algebra: The base-N log of a number is equal to the natural log of that number divided by the natural log of N. For example:sub log10 { my $n = shift; return log($n)/log(10); }See also
expfor the inverse operation.
