Floor Rounding In C

Syntax for floor function in c is given below.

Floor rounding in c.

The floor function returns the largest integer that is smaller than or equal to x. If decimal value is from 1 to 5 it returns integer value less than the argument. 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.

Header tgmath h provides a type generic macro version of this function. The math round function allows you to find the closest integer value of a given number. Round down value rounds x downward returning the largest integral value that is not greater than x. In this program we are going to find the closest integer value of different numbers and display the output.

C round function example. This kind of rounding is sometimes called rounding toward negative infinity. Parameters or arguments x the value to round down to the nearest integer. Round function in c returns the nearest integer value of the float double long double argument passed to this function.

Double floor double x. Rounding floating point number to two decimal places in c and c setting decimal precision in c precision of floating point numbers in c floor ceil trunc round and setprecision. In the c programming language the floor function returns the largest integer that is smaller than or equal to x ie. The following example illustrates the math floor double method and contrasts it with the ceiling double method.
