This function returns the absolute value of its argument. If a pure integer value is passed then it will return it as it is, but if a string is passed then it will return zero. If VALUE is omitted then it uses $_
Syntax: abs(VALUE) Parameter: VALUE: It is a required number which can be either positive or negative or a string. Returns: Function returns the absolute value of the arguments passed.
Example 1:
#!/usr/bin/perl
  
# Defining decimal value
$var1 = 15.8;
  
# Defining integer value
$var2 = 7;
  
# Defining negative value
$var3 = "-15.2";
  
# Calling abs() function
$res1 = abs($var1);
$res2 = abs($var2);
$res3 = abs($var3);
  
# Printing these values
print "Abs value of var1 is $res1\n";
print "Abs value of var2 is $res2\n";
print "Abs value of var3 is $res3";

                    
Output:
