Code #1 : Example for logb() method
# Python Program explaining # logb() method # loading decimal library from decimal import * # Initializing a decimal value a = Decimal('.9932') b = Decimal('0.142857') # printing Decimal values print ("Decimal value a : ", a) print ("Decimal value b : ", b) # Using Decimal.logb() method print ("\n\nDecimal a with logb() method : ", a.logb()) print ("Decimal b with logb() method : ", b.logb()) |
Output :
Decimal value a : 0.9932 Decimal value b : 0.142857 Decimal a with logb() method : -1 Decimal b with logb() method : -1
Code #2 : Example for logb() method
# Python Program explaining # logb() 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.logb() method print ("\n\nDecimal a with logb() method : ", a.logb()) print ("Decimal b with logb() method : ", b.logb()) |
Output :
