Code #1 : Example for log10() method
# 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()) |
Output :
Decimal value a : 0.9932 Decimal value b : 0.142857 Decimal a with log10() method : -0.002963289117473302730973454338 Decimal b with log10() method : -0.8450984743089558813497604715
Code #2 : Example for log10() method
# Python Program explaining # log10() 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.log10() method print ("\n\nDecimal a with log10() method : ", a.log10()) print ("Decimal b with log10() method : ", b.log10()) |
Output :
Decimal value a : 3.14 Decimal value b : 3.21E+7 Decimal a with log10() method : 0.4969296480732149319752200246 Decimal b with log10() method : 7.506505032404872078129569143
