• Last Updated : 05 Sep, 2019

Decimal#compare() : compare() is a Decimal class method which compares the two Decimal values.

Syntax: Decimal.compare()

Parameter: Decimal values

Return:
1 – if a > b
-1 – if a < b
0 – if a = b

Code #1 : Example for compare() method

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

Output :

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

Decimal a with compare() method :  0
Decimal a with compare() method :  -1
Decimal b with compare() method :  1

```

Code #2 : Example for compare() method

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

Output :

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

Decimal a with compare() method :  0
Decimal a with compare() method :  -1
Decimal b with compare() method :  1
