Floor function in math h.

Floor double x long. C floor prototype double floor double arg the floor function takes a single argument and returns the value in type double. These overloads effectively cast x to a double before calculations defined for t being any integral type. The floor function returns the largest integer that is smaller than or equal to x.

Additional overloads are provided in this header cmath for the integral types. Required header in the c language the required header for the floor function is. Example round to largest integral value not greater than x. C library function floor the c library function double floor double x returns the largest integer value less than or equal to x.

251 7 25 type generic math tgmath h p. 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. 373 375 f 10 6 2 the floor functions p. Header tgmath h provides a type generic macro version of this function.

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. Some basic mathematical calculations are based on the concept of floor and ceiling. It is defined in math h header file.

C11 standard iso iec 9899 2011. Syntax for floor function in c is given below. If 2 3 is passed to ceil it will return 3. Double floor double x.

All the functions available in this library take double as an argument and return double as the result. The function is defined in math h header file. There is only one macro defined in this library. Math h header file supports floor function in c language.
