Ceiling And Floor Function C
In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.
Ceiling and floor function c. Some basic mathematical calculations are based on the concept of floor and ceiling. Ceil and floor functions in c last updated. Floor function in c returns the nearest integer value which is less than or equal to the floating point argument passed to this function. 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.
Additional overloads are provided in this header cmath for the integral types. In the c programming language the ceil function returns the smallest integer that is greater than or equal to x ie. For ceiling and. The ceiling function is usually denoted by ceil x or less commonly ceiling x in non apl computer languages that have a notation for this function.
The int function short for integer is like the floor function but some calculators and computer programs show different results when given negative numbers. Syntax for floor function in c is given below. The datatype of variable should be double float long double only. Double floor double x.
