# Python | Decimal compare_total_mag() method

Last Updated : 05 Sep, 2019

Decimal#compare_total_mag() : compare_total_mag() is a Decimal class method which compares the two Decimal values by using their abstract representation rather than their value, but ignoring the sign of each operand.

```Syntax:
Decimal.compare_total_mag()

Parameter:
Decimal values

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

```

Code #1 : Example for compare_total_mag() method

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

Output :

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

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

```

Code #2 : Example for compare_total_mag() method

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

Output :

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

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