The ceil function in c returns the smallest possible integer value which is greater than or equal to the given argument.
This function is also declared in cmath header file in c language.
C library function floor the c library function double floor double x returns the largest integer value less than or equal to x.
C allows overloading so you can call overloads of floor that take and return float and long double values.
Header tgmath h provides a type generic macro version of this function.
In a c program unless you re using the tgmath h macro to call this function floor always takes and returns.
In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or.
It takes single value whoes floor value is to be calculated.
