float- holds floating decimal points and it's accurate up to15decimal places. complex- holds complex numbers. We can use thetype()function to know which class a variable or a value belongs to. Let's see an example, num1 =5print(num1,'is of type', type(num1)) num2 =2.0print(num...
timeit( string, number=1000000, globals=globals() ) * 1000 print(f"{tool}: {time:>{max_length - len(tool) + 6}.2f} ms") run_performance_test(strings) In this script, the run_performance_test() function takes care of measuring the execution time of the three different string ...
print(division) again = decimal.Decimal(72) / decimal.Decimal(7) print(again) 1. 2. 3. 4. 5. 6. 7. 8. 9. We did the division operation two times to prove a point. Let’s see the output for this program: Noticed something? The precision we set was only valid for a single ti...

print(x) print("---") x = Decimal('0.1') + Decimal('0.1') + Decimal('0.1') print(x == Decimal('0.3')) print(float(x) == 0.3) print(x) The example performs a comparison of floating point values with the built-infloatand theDecimaltypes. $ ./comparing.py False 0.300000000000000...
print(f'{val:.2f}') print(f'{val:.5f}') The example prints a formatted floating point value. $ python main.py 12.30 12.30000 The output shows the number having two and five decimal places. Thousands separators We can format numbers with underscore and command thousands separators. ...
