Floor function in cpp.
This function is also declared in cmath header file in c language.
The floor function takes a single argument and returns a value of type double float or long double type.
In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or.
This function is defined in cmath header file.
In a c program unless you re using the tgmath h macro to call this function floor always takes and returns.
Floor has an implementation that uses streaming simd extensions 2 sse2.
The ceil function in c returns the smallest possible integer value which is greater than or equal to the given argument.
