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 programming example.
Floor function returns the greatest integer 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.
C floor the floor function calculates the nearest integer less than the argument passed.
If 2 3 is passed to ceil it will return 3.
C library function ceil the c library function double ceil double x returns the smallest integer value greater than or equal to x.
For example if the input is 2 25 then the output will be 2 00.
The ceil function takes a single argument and returns a value of type int.
Both functions are library functions and declare in math h header file.
In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or.
Double floor double x.
Floor function in c returns the nearest integer value which is less than or equal to the floating point argument passed to this function.
C ceil prototype double ceil double arg.
Math h header file supports floor function in c language.
Syntax for floor function in c is given below.
Rounds downs the nearest integer.
For example and while.
Some basic mathematical calculations are based on the concept of floor and ceiling.
Syntax the syntax for the floor function in the c language is.
