Ralf Muschall He probably simply meant "do the right thing", the inventors of Lisp and Scheme followed that way (it *is* mainly their philosophy), and Guido followed them :-) Finding now that Python does the right thing is just a tautology, and saving the few cycles by doing the bad thing makes no sense in an interpreted language.

Round() is a built-in function available with python. 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). n − Represents number of digits from decimal point up … If you get 10/3 as 3, then that suggests you're using python 2, which has different semantics for floating point division and integer division. Syntax. There's a python tutorial on the subject of floating point and rounding. The default number of decimals is 0, meaning that the function will return the nearest integer. 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).. That sounds abstract, but is just another way of saying that math.floor() rounds down to the next whole number. round( x [, n] ) Parameters. ..b) if a decimal number is given , then it will round off to the ceil integer after that if decimal value has >=5 , and it will round off to the floor integer if decimal is <5.
