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.
Floor function returns the greatest integer not greater than x.
Double floor double x float floor float.
Syntax for floor function in c is given below.
Some basic mathematical calculations are based on the concept of floor and ceiling.
Rounds downs the nearest integer.
In the c programming language the required header file for floor function is.
For example if the input is 2 25 then the output will be 2 00.
Math h header file supports floor function in c language.
Suppose num 12 1 then floor num returns 12 header file.
Syntax the syntax for the floor function in the c language is.
Floor is also called as round down floorl function evaluates floorl finds the largest long double integer not greater than x returns the largest integral value that is not greater than 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.
In the c programming language the floor function returns the largest integer that is smaller than or equal to x ie.
In most programming languages the simplest method to convert a floating point number to an integer does not do floor or ceiling but truncation the reason for this is historical as the first machines used ones complement and truncation was simpler to implement floor is simpler in two s complement.
Fortran was defined to require this behavior and thus almost all processors implement.
Double floor double x.
C floor the floor function calculates the nearest integer less than the argument passed.
