In Perl, you can convert an integer to a floating-point number (float) simply by dividing it by a float number or adding a float number to it.
Here's an example:
my $integer = 5;
my $float = $integer / 2.0;
print "Float: $float";
In this example, we divide the integer 5 by the float 2.0 using the / operator and assign the resulting float value 2.5 to a variable named $float. We then print the $float variable to confirm that it is indeed a float.
Another way to convert an integer to a float is to use decimal notation in the integer. For example:
my $integer = 5;
my $float = $integer + 0.0;
print "Float: $float";
Here, we add 0.0 to the integer 5 using the + operator, which causes Perl to interpret 5 as a float value and assign the resulting float value 5.0 to a variable named $float. We then print the $float variable to confirm that it is indeed a float.
Both of these methods are simple ways of converting an integer to a floating-point number in Perl.
