CompTIA Linux+ XK0-006 (V8) Practice Question

A Python 3 script running on a Linux server needs to determine whether a newly-calculated metric is equal to an expected value. The developer tried:

if 0.1 + 0.2 == 0.3:
    send_alert()

but discovered that the condition evaluates to False because of binary floating-point representation. Which standard-library function, added in Python 3.5, offers a reliable way to test whether two floating-point numbers are approximately equal within a user-defined tolerance?

  • math.isclose()

  • statistics.close()

  • sys.float_compare()

  • math.equal()
