Double floor double x. It takes single value whoes floor value is to be calculated. 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 mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.

The floor of 2 31 is 2 the ceiling of 2 31 is 3. Additional overloads are provided in this header cmath for the integral types. The ceil function takes a single argument and returns a value of type int. Math h floor function example in c.

These overloads effectively cast x to a double before calculations defined for t being any integral type. C library function ceil the c library function double ceil double x returns the smallest integer value greater than or equal to x. 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. Rounds downs the nearest integer.

You can store the result and use it in whichever way you want to. Math h header file supports floor function in c language. If 2 3 is passed to ceil it will return 3. Syntax for floor function in c is given below.
