• log EXPR

• log

  Returns the natural logarithm (base e) of EXPR. If EXPR is omitted,returns the log of $_. To get thelog of another base, use basic algebra:The base-N log of a number is equal to the natural log of that numberdivided by the natural log of N. For example:

   sub log10 {
   
   my $n = shift;
   
   return log($n)/log(10);
   
   }
   

  See also exp for the inverse operation.
