Perl | Math::BigInt->binf() method

Last Updated : 03 Oct, 2019

Math::BigInt module in Perl provides objects that represent integers with arbitrary precision and overloaded arithmetical operators.

binf() method of Math::BigInt module is used to create a new object with value infinity and if used on an existing object, it sets it to infinity.

Syntax: Math::BigInt->binf()

Parameter:
plus or minus: to set the sign of infinity as ‘+’ or ‘-‘

Returns: object with value inf

Example 1:

#!/usr/bin/perl   
    
# Import Math::BigInt module  
use Math::BigInt;  
   
# Create a BigInt object  
$x = Math::BigInt->binf(); 
  
# Object created with binf() 
print("$x\n"); 
  
# Create a BigInt object  
$x = Math::BigInt->binf('-'); 
  
# Object created with binf() 
print("$x"); 

Output:

inf
-inf

Example 2:

#!/usr/bin/perl   
    
# Import Math::BigInt module  
use Math::BigInt;  
    
# Specify number  
$num = 78215936043546;  
    
# Create BigInt object  
$x = Math::BigInt->new($num);  
  
# Object before function call 
print("Before function call: $x\n");  
  
# Calling the function 
$x->binf(); 
  
# Object after function call 
print("After function call: $x"); 

Output:

Before function call: 78215936043546
After function call: inf

Example 3:

#!/usr/bin/perl   
    
# Import Math::BigInt module  
use Math::BigInt;  
    
# Specify number  
$num = 78215936043546;  
    
# Create BigInt object  
$x = Math::BigInt->new($num);  
  
# Object before function call 
print("Before function call: $x\n");  
  
# Calling the function with '-' sign 
$x->binf('-'); 
  
# Object after function call 
print("After function call: $x"); 

Output:

Before function call: 78215936043546
After function call: -inf
