Floor has an implementation that uses streaming simd extensions 2 sse2.
Floor int c.
C floor the floor function in c returns the largest possible integer value which is less than or equal to the given argument.
Rounds downs the nearest integer.
In a c program unless you re using the tgmath h macro to call this function floor always takes and returns.
However the result may overflow any integer type including std intmax t when stored in an integer variable.
Otherwise if arg has integer type or the type double floor is called.
Float floor float x.
If arg has type long double floorl is called.
Float ceil float x.
This function is also declared in cmath header file in c language.
Additional overloads for integral types.
In the c language the required header for the floor function is.
1 3 computes the largest integer value not greater than arg.
It takes single value whoes floor value is to be calculated.
Long double floor long double x.
Double ceil double x.
The floor function returns the largest possible integer value which is equal to the value or smaller than that.
Here x is the floating point value.
Include math h applies to.
C allows overloading so you can call overloads of floor that take and return float and long double values.
Double ceil t x.
Returns the largest integer that is smaller than or equal to x i e.
Double floor double x.
In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.
For information and restrictions about using the sse2 implementation see set sse2 enable.
Long double ceil long double x.
Round down value rounds x downward returning the largest integral value that is not greater than x.
