Add logic to print two lines. The round() function returns a floating point number that is a rounded version of the specified number, with the specified number of decimals.. No rounding … The math.floor() function returns the floor value of its argument, which is the nearest integer less than or equal to that argument's value (Python Docs, n.d. b)..

Python int() Function Built-in Functions ... x = int(3.5) Try it Yourself » Definition and Usage. For one thing, the result is ill-defined unless you control the rounding mode used by HW float division (4.0 / 0.4 == 10.0 only if the rounding mode is to-nearest/even or to-plus-infinity; it's 1 ULP less if to-minus-infinity or to-zero; then taking the floor gives 10 in the former cases but 9 in the latter). The second line should contain the result of float division, / . x − This is a numeric expression.. n − This is also a numeric expression.. Return Value.
