Floor Function In C Programming

C library function floor the c library function double floor double x returns the largest integer value less than or equal to x.

Floor function in c programming.

Some basic mathematical calculations are based on the concept of floor and ceiling. 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. C floor the floor function calculates the nearest integer less than the argument passed.

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. Rounds downs the nearest integer. For example if the input is 2 25 then the output will be 2 00. Double floor double x.

Double floor double x float floor float. Syntax the syntax for the floor function in the c language is. 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.

Submitted by manu jemini on march 17 2018. In the c programming language the required header file for floor function is. Floor function in c returns the nearest integer value which is less than or equal to the floating point argument passed to this function. Math h header file supports floor function in c language.

Fortran was defined to require this behavior and thus almost all processors implement. Syntax for floor function in c is given below.
