# Python Program explaining # log10() 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.log10() method print ( "\n\nDecimal a with log10() method : " , a.log10())
print ( "Decimal b with log10() method : " , b.log10())
