In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.
Floor int c.
1 3 computes the largest integer value not greater than arg.
Double ceil double x.
Additional overloads for integral types.
The value to round down to the nearest integer.
Float floor float x.
Long double ceil long double x.
C floor the floor function in c returns the largest possible integer value which is less than or equal to the given argument.
Floor has an implementation that uses streaming simd extensions 2 sse2.
Include math h applies to.
The floor function returns the largest possible integer value which is equal to the value or smaller than that.
Round down value rounds x downward returning the largest integral value that is not greater than x.
This function is also declared in cmath header file in c language.
The largest representable floating point values are exact integers in all standard floating point formats so this function never overflows on its own.
The floor function returns the largest integer that is smaller than or equal to x.
However the result may overflow any integer type including std intmax t when stored in an integer variable.
Float ceil float x.
Rounds downs the nearest integer.
It takes single value whoes floor value is to be calculated.
For information and restrictions about using the sse2 implementation see set sse2 enable.
Returns the largest integer that is smaller than or equal to x i e.
Double floor double x.
C allows overloading so you can call overloads of floor that take and return float and long double values.
Long double floor long double x.
Here x is the floating point value.
If arg has type long double floorl is called.
In the c language the required header for the floor function is.
