perl function log

In Perl, the log function is used to calculate the natural logarithm of a given number. The natural logarithm of a number x is the power to which the mathematical constant e (approximately equal to 2.71828) must be raised to obtain x.

Here's an example that demonstrates how to use log:

#!/usr/bin/perl

use strict;
use warnings;

# Calculate the natural logarithm of 10
my $x = log(10);

# Print the result
print "log(10) = $x\n";

In this example, we use the log function to calculate the natural logarithm of the number 10. We store the result in a variable named $x. Finally, we print the result using the print function.

When we run this script, it will calculate the natural logarithm of 10 and print the result:

log(10) = 2.30258509299405

This indicates that the natural logarithm of 10 is approximately equal to 2.30258509299405.
