Code #1 : Example for is_zero() method

 `# Python Program explaining  ` `# is_zero() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``-``1``) ` ` `  `b ``=` `Decimal(``0``) ` ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.is_zero() method ` `print` `(``"\n\nDecimal a with is_zero() method : "``, a.is_zero()) ` ` `  `print` `(``"Decimal b with is_zero() method : "``, b.is_zero()) `

Output :

```Decimal value a :  -1
Decimal value b :  0

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

```

Code #2 : Example for is_zero() method

 `# Python Program explaining  ` `# is_zero() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``-``0``) ` ` `  `b ``=` `Decimal(``'321e + 5'``) ` ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.is_zero() method ` `print` `(``"\n\nDecimal a with is_zero() method : "``, a.is_zero()) ` ` `  `print` `(``"Decimal b with is_zero() method : "``, b.is_zero()) `

Output :

```Decimal value a :  0
Decimal value b :  3.21E+7

Decimal a with is_zero() method :  True
