Ceiling and floor functions 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. Rounds downs the nearest integer. Additional overloads are provided in this header cmath for the integral types. The floor function returns the largest possible integer value which is equal to the value or smaller than that.

The floor of 2 31 is 2 the ceiling of 2 31 is 3. Rounds up the nearest integer. Math h header file supports floor function in c language. The floor and ceiling functions give us the nearest integer up or down.

Ceiling function in mathematics and computer science the floor function is the function that takes as input a real number displaystyle x and gives as output the greatest integer less than or equal to displaystyle x denoted. Returns the largest integer that is smaller than or equal to x i e. Math h floor function example in c. C ceil prototype double ceil double arg.

These overloads effectively cast x to a double before calculations defined for t being any integral type. The ceil function takes a single argument and returns a value of type int. This function is also declared in cmath header file in c language. It takes single value whoes floor value is to be calculated.

Header tgmath h provides a type generic macro version of this function. To use floor and ceil functions all you need to do is pass a number as a parameter and these function will return a number satisfying the above explained concept. Syntax for floor function in c is given below. You can store the result and use it in whichever way you want to.
