Floor Function C Math H

The function is defined in math h header file.

Floor function c math h.

C floor prototype double floor double arg the floor function takes a single argument and returns the value in type double. Header tgmath h provides a type generic macro version of this function. Math h header file supports floor function in c language. These overloads effectively cast x to a double before calculations defined for t being any integral type.

All the functions available in this library take double as an argument and return double as the result. Submitted by manu jemini on march 17 2018. There is only one macro defined in this library. Additional overloads are provided in this header cmath for the integral types.

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. Floor function in c returns the nearest integer value which is less than or equal to the floating point argument passed to this function. The ceil function takes a single argument and returns a value of type int. It is defined in math h header file.

Syntax for floor function in c is given below. Some basic mathematical calculations are based on the concept of floor and ceiling. Double floor double x. C library function floor the c library function double floor double x returns the largest integer value less than or equal to x.

The math h header defines various mathematical functions and one macro.
