Floor Function C Math H

All the functions available in this library take double as an argument and return double as the result.

Floor function c math h.

Floor function in c returns the nearest integer value which is less than or equal to the floating point argument passed to this function. There is only one macro defined in this library. The floor function returns the largest integer that is smaller than or equal to x. Header tgmath h provides a type generic macro version of this function.

If 2 3 is passed to ceil it will return 3. Additional overloads are provided in this header cmath for the integral types. C library function floor the c library function double floor double x returns the largest integer value less than or equal to x. These overloads effectively cast x to a double before calculations defined for t being any integral type.

Some basic mathematical calculations are based on the concept of floor and ceiling. Double floor double x. The ceil function takes a single argument and returns a value of type int. The math h header defines various mathematical functions and one macro.

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. Required header in the c language the required header for the floor function is. Math h header file supports floor function in c language. C floor prototype double floor double arg the floor function takes a single argument and returns the value in type double.
