Code #1 : Example for scaleb() method

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

Output :

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

Decimal a with scaleb() method :  1
Decimal b with scaleb() method :  0

```

Code #2 : Example for scaleb() method

 `# Python Program explaining  ` `# scaleb() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``3``) ` ` `  `b ``=` `Decimal(``2``) ` ` `  ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.scaleb() method ` `print` `(``"\n\nDecimal a with scaleb() method : "``, a.scaleb(b)) ` ` `  `print` `(``"Decimal b with scaleb() method : "``, b.scaleb(b)) `

Output :

```Decimal value a :  3
Decimal value b :  2

Decimal a with scaleb() method :  3E+2
Decimal b with scaleb() method :  2E+2
