# Python | Decimal is_qnan() method

• Last Updated : 05 Sep, 2019

Decimal#is_qnan() : is_qnan() is a Decimal class method which checks whether the Decimal value is quite NaN value.

Syntax: Decimal.is_qnan()

Parameter: Decimal values

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

Code #1 : Example for is_qnan() method

 `# Python Program explaining ``# is_qnan() 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_qnan() method``print` `(``"\n\nDecimal a with is_qnan() method : "``, a.is_qnan())`` ` `print` `(``"Decimal b with is_qnan() method : "``, b.is_qnan())`

Output :

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

Decimal a with is_qnan() method :  False
Decimal b with is_qnan() method :  True

```

Code #2 : Example for is_qnan() method

 `# Python Program explaining ``# is_qnan() 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_qnan() method``print` `(``"\n\nDecimal a with is_qnan() method : "``, a.is_qnan())`` ` `print` `(``"Decimal b with is_qnan() method : "``, b.is_qnan())`

Output :

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

Decimal a with is_qnan() method :  False
Decimal b with is_qnan() method :  False
```
