WebNov 13, 2024 · Before you can apply the floor function, you need to evaluate the logarithm. The logarithm can be simplified, as you did log 2 ( n 2) = log 2 n − log 2 2 and hence your second solution follows. Note that the used formula (with a = log 2 n and x = − log 2 2) ⌊ a + x ⌋ = ⌊ a ⌋ + x only works when x ∈ Z (as in this case, where log 2 2 = 1 ). WebAug 17, 2024 · Definition 1.4.1. If x is any real number we define ⌊x⌋ = the greatest integer less than or equal to x ⌈x⌉ = the least integer greater than or equal to x. ⌊x⌋ is called the floor of x and ⌈x⌉ is called the ceiling of x The floor ⌊x⌋ is sometimes denoted [x] and called the greatest integer function. But I prefer the notation ...

Floor function of any real number x gives us the largest integer less than or equal to x. For example, if we have x =4.1, then the floor function of x gives us 4, which is the largest integer less than 4.1. What is Ceiling Function? howard-winneshiek community school district
