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. Syntax for floor function in c is given below. Floor function in c returns the nearest integer value which is less than or equal to the floating point argument passed to this function. Double floor double x.
