Perl | abs() function

Last Updated : 25 Jun, 2019

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:

Abs value of var1 is 15.8
Abs value of var2 is 7
Abs value of var3 is 15.2

Example 2:

#!/usr/bin/perl 
  
# Defining string value 
$var1 = "Geeks"; 
  
# Defining Fractional value 
$var2 = 7/2; 
  
# Calling abs() function 
$res1 = abs($var1); 
$res2 = abs($var2); 
  
# Print these values 
print "Abs value of var1 is $res1\n"; 
print "Abs value of var2 is $res2"; 

Output:

Abs value of var1 is 0
Abs value of var2 is 3.5

Perl | int() function

int() function in Perl returns the integer part of given value. It returns $_ if no value provided. Note that $_ is default input which is 0 in this case. The int() function does not do rounding. For rounding up a value to an integer, sprintf is used. Syntax: int(VAR) Parameters: VAR: value which is

Perl | oct() Function

oct() function in Perl converts the octal value passed to its respective decimal value. For example, oct('1015') will return '525'. This function returns the resultant decimal value in the form of a string which can be used as a number because Perl automatically converts a string to a number in nume
