• Last Updated : 09 Sep, 2019

Decimal#next_minus() : next_minus() is a Decimal class method which returns the largest representable number smaller than the Decimal value.

Syntax: Decimal.next_minus()

Parameter: Decimal values

Return: the largest representable number smaller than the Decimal value.

Code #1 : Example for next_minus() method

 `# Python Program explaining  ` `# next_minus() method ` ` `  `# loading decimal library ` `from` `decimal ``import` `*` ` `  ` `  `# Initializing a decimal value ` `a ``=` `Decimal(``-``1``) ` ` `  `b ``=` `Decimal(``'0.142857'``) ` ` `  `# printing Decimal values ` `print` `(``"Decimal value a : "``, a) ` `print` `(``"Decimal value b : "``, b) ` ` `  ` `  `# Using Decimal.next_minus() method ` `print` `(``"\n\nDecimal a with next_minus() method : "``, a.next_minus()) ` ` `  `print` `(``"Decimal a with next_minus() method : "``, a.next_minus()) ` ` `  `print` `(``"Decimal b with next_minus() method : "``, b.next_minus()) `

Output :

```Decimal value a :  -1
Decimal value b :  0.142857

Decimal a with next_minus() method :  -1.000000000000000000000000001
Decimal a with next_minus() method :  -1.000000000000000000000000001
Decimal b with next_minus() method :  0.1428569999999999999999999999

```

Code #2 : Example for next_minus() method

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

Output :

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

Decimal a with next_minus() method :  -3.140000000000000000000000001
Decimal a with next_minus() method :  -3.140000000000000000000000001
Decimal b with next_minus() method :  32099999.99999999999999999999
