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

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:

perl

#!/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:

perl

#!/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:

perl

#!/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
