I'm converting from all units of time to seconds and for some reason with the smaller units of time (picoseconds and femtoseconds), i'm getting (femtoseconds): 0.00000000000000100000000000000007770539987666107923830718560119501514549256171449087560176849365234375 instead of 0.000000000000001.有誰(shuí)知道為什么？days = int(input("Enter the amount of days: ")) * 24 * 60 * 60hours = int(input("Enter the amount of hours: ")) * 60 * 60minutes = int(input("Enter the amount of minutes: ")) * 60ms = int(input("Enter the amount of milliseconds: ")) * (10 ** -3)mcs = int(input("Enter the amount of microseconds: ")) * (10 ** -6)ns = int(input("Enter the amount of nanoseconds: ")) * (10 ** -9)ps = int(input("Enter the amount of picoseconds: ")) * (10 ** -12)fs = int(input("Enter the amount of femtoseconds: ")) * (10 ** -15)s = days + hours + minutes + ms + mcs + ns + ps + fsprint("The amount of seconds is:", "{0:.50}".format(s))
