Floor Function In C Programming

Rounds downs the nearest integer.

Floor function in c programming.

Fortran was defined to require this behavior and thus almost all processors implement. C library function floor the c library function double floor double x returns the largest integer value less than or equal to x. 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. 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.

In the c programming language the required header file for floor function is. Math h header file supports floor function in c language. Double floor double x float floor float. Floor function in c returns the nearest integer value which is less than or equal to the floating point argument passed to this function.

Floor function returns the greatest integer not greater than x. For example if the input is 2 25 then the output will be 2 00. Syntax the syntax for the floor function in the c language is. Double floor double x.

Syntax for floor function in c is given below. In the c programming language the floor function returns the largest integer that is smaller than or equal to x ie. The following example explains the usage of floor function. When a value for x is passed this function returns the floor value of x largest integer value which is less than or equal to the passed value.

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. C floor the floor function calculates the nearest integer less than the argument passed.
