perl function int

The int function in Perl is used to round a floating-point number down to the nearest integer. It takes one argument, which is the number to round.

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

#!/usr/bin/perl

use strict;
use warnings;

# Round a floating-point number down to the nearest integer
my $number = 3.14;
my $integer = int($number);

# Print the result
print "Number: $number\n";
print "Integer: $integer\n";

In this example, we start by defining a floating-point number 3.14. We then use the int function to round this number down to the nearest integer. Since 3 is the nearest integer below 3.14, int returns 3. We assign this value to a variable called $integer.

We then print both the original number and the rounded integer to the console using print.

Note that the int function always rounds down to the nearest integer, even if the original number is negative. If you need to round to the nearest integer, you can use the sprintf function with a format string that includes a precision specifier.
