Decimal#max_mag() : max_mag() is a Decimal class method which compares the two Decimal values and return the max of two, with their sign ignored.

```Syntax:  Decimal.max_mag()

Parameter:  Decimal values

Return:  the max_mag of two, with their sign ignored.
```

Code #1 : Example for max_mag() method

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

Output :

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

Decimal a with max_mag() method :  -1
Decimal a with max_mag() method :  -1
Decimal b with max_mag() method :  -1
```

Code #2 : Example for max_mag() method

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

Output :

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

Decimal a with max_mag() method :  -3.14
Decimal a with max_mag() method :  3.21E+7
Decimal b with max_mag() method :  3.21E+7
