The Math.ceil () function always rounds up and returns the smaller integer greater than or equal to a given number. This question has some nice answers about the behaviour before Python 3. The Golang math.Ceil() function returns the next highest integer value by rounding up value of a floating poing number if necessary. It is defined in the cmath header file.. Note that at very large values (positive or negative) the numbers end up being distributed very sparsely - so the next integer greater than integer x won't be x + 1 if you see what I mean. floor would have been chosen to match the standard c routine in math.h (rint, mentioned in another answer, is also present in that library, and returns a double, as in java).. but round was not a standard function in c at that time (it's not mentioned in C89 - c identifiers and standards; c99 does define round and it returns a double, as you would expect). Definition and Usage. Python math.ceil() Method - W3Schools Therefore, if we round down beyond the lowest 32-bit signed integer value (-2,147,483,648), we will no longer be within the range of an int(likewise for long).
