Code #1 : Example for to_eng_string() method

 `# Python Program explaining  ` `# to_eng_string() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``1.898989``) ` ` `  `b ``=` `Decimal(``2.0``) ` ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.to_eng_string() method ` `print` `(``"\n\nDecimal a with to_eng_string() method : "``, a.to_eng_string()) ` ` `  `print` `(``"Decimal b with to_eng_string() method : "``, b.to_eng_string()) `

Output :

```Decimal value a :  1.8989890000000000380708797820261679589748382568359375
Decimal value b :  2

Decimal a with to_eng_string() method :  1.8989890000000000380708797820261679589748382568359375
Decimal b with to_eng_string() method :  2

```

Code #2 : Example for to_eng_string() method

 `# Python Program explaining  ` `# to_eng_string() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``3.14``) ` ` `  `b ``=` `Decimal(``15``) ` ` `  ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.to_eng_string() method ` `print` `(``"\n\nDecimal a with to_eng_string() method : "``, a.to_eng_string()) ` ` `  `print` `(``"Decimal b with to_eng_string() method : "``, b.to_eng_string()) `

Output :

```Decimal value a :  3.140000000000000124344978758017532527446746826171875
Decimal value b :  15

Decimal a with to_eng_string() method :  3.140000000000000124344978758017532527446746826171875
Decimal b with to_eng_string() method :  15
