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

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

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

Syntax: Math::BigInt->bnan()

Parameter: No Parameter

Returns: NAN(Not A Number)

Example 1:

#!/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->bnan();

# Object after function call
print("After function call: $x");

Output:

Before function call: 78215936043546
After function call: NaN

Example 2:

#!/usr/bin/perl

# Import Math::BigInt module
use Math::BigInt;

# Create a BigInt object
$x = Math::BigInt->bnan();

# Object created with bnan()
