Amal Benny, This is because of how floating point numbers are represented in almost every programming languages. https://docs.python.org/3/tutorial/floatingpoint.html

Use: round(your_float, 2) so it will be float with 2 digits after a dot.

Amal Benny By default Python don't stop at double-precision after the 2 digits. sol- print("{:.2f}".format(dc_frk))
