Python | Decimal is_snan() method

Decimal#is_snan() : is_snan() is a Decimal class method which checks whether the Decimal value is a signaling NaN

Syntax: Decimal.is_snan()

Parameter: Decimal values

Return: true – if the Decimal value is a signaling NaN; otherwise false

Code #1 : Example for is_snan() method

 `# Python Program explaining  ` `# is_snan() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``-``1``) ` ` `  `b ``=` `Decimal(``'nan'``) ` ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.is_snan() method ` `print` `(``"\n\nDecimal a with is_snan() method : "``, a.is_snan()) ` ` `  `print` `(``"Decimal b with is_snan() method : "``, b.is_snan()) `

Output :

```Decimal value a :  -1
Decimal value b :  -NaN

Decimal a with is_snan() method :  False
Decimal b with is_snan() method :  False

```

Code #2 : Example for is_snan() method

 `# Python Program explaining  ` `# is_snan() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``'-3.14'``) ` ` `  `b ``=` `Decimal(``'321e + 5'``) ` ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.is_snan() method ` `print` `(``"\n\nDecimal a with is_snan() method : "``, a.is_snan()) ` ` `  `print` `(``"Decimal b with is_snan() method : "``, b.is_snan()) `

Output :

```Decimal value a :  -3.14
Decimal value b :  3.21E+7

Decimal a with is_snan() method :  False
Decimal b with is_snan() method :  False
