Did the same mistake in one of my onsites 😂. Don’t know how ceil works in python. In java we need to explicitly typecast it to double while calling ceil. 3/6 goes as integer division, math.ceil(3/6) is basically math.ceil(0), so it’s returning 0.0. While Math.ceil(3/(double)6) return 1.0. More on reddit.com

CEIL
November 12, 2025 - CEIL returns the smallest integer that is greater than or equal to n. The number n can always be written as the difference of an integer k and a positive fraction f such that 0 <= f < 1 and n = k - f. The value of CEIL is the integer k. Thus, the value of CEIL is n itself if and only if n is ...
