The floor function returns the largest possible integer value which is equal to the value or smaller than that.

Floor has an implementation that uses streaming simd extensions 2 sse2. This function is also declared in cmath header file in c language. 4 a set of overloads or a function template accepting an argument of any integral type. Returns the largest integer that is smaller than or equal to x i e.

The modulo division operator produces the remainder of an integer division. For information and restrictions about using the sse2 implementation see set sse2 enable. Additional overloads for integral types round down value rounds x downward returning the largest integral value that is not greater than x. Rounds downs the nearest integer.

In a c program unless you re using the tgmath h macro to call this function floor always takes and returns. The floor function in c returns the largest possible integer value which is less than or equal to the given argument. If x and y are integers then the expression.
