WebOct 2, 2024 · f = { R → Z x ↦ z = inf ( x) Explanation: The floor function maps a real number x to the smallest whole number less than or equal to x. The infimum of is the largest lower bound of a set. The above stated function f maps a real number x to the largest whole number z for which z ≤ x, which is the definition of the floor function. Hence f = floor. WebApr 8, 2010 · floor (n) returns the mathematical floor of n, that is, the greatest integer not greater than n. (int)n returns the truncation of n, the integer whose absolute value is no greater than that of n. Similarly, ceil (n) returns the mathematical ceiling of n, or the smallest integer not smaller than n.

The math.floor () always returns the closest lower integer value. Keeping this thing in mind, -20<-19.8<-19 So -20 is returned as expected. On the other hand for positive integers, say 5.5, 5<5.5<6, So math.floor () would return 5 here. Share Follow quick change toilet roll holder
