C Std Floor Int
In the c programming language the floor function returns the largest integer that is smaller than or equal to x ie.
C std floor int. Double floor double x. 1 3 computes the largest integer value not greater than arg. Floor has an implementation that uses streaming simd extensions 2 sse2. The largest representable floating point values are exact integers in all standard floating point formats so this function never overflows on its own.
Long double floor long double x. If arg has type long double floorl is called. Syntax the syntax for the floor function in the c language is. Float floor float x.
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. For information and restrictions about using the sse2 implementation see set sse2 enable. Rounds downs the nearest integer.
C floor the floor function in c returns the largest possible integer value which is less than or equal to the given argument.
