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