For integral type. In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively. In this article we are going to learn about the floor and ceil functions of math h header file in c language and use them with help of their examples. This function is declared in cmath header file in c language.

C allows overloading so you can call overloads of floor that take and return float and long double values. In a c program unless you re using the tgmath h macro to call this function floor always takes and returns a double. The language apl uses x.
