NAME
floor, floorf, floorl - floor function SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <math.h> double floor(double x); float floorf(float x); long double floorl(long double x); DESCRIPTION
These functions compute the largest integral value not greater than x. RETURN VALUES
Upon successful completion, these functions return the largest integral value not greater than x, expressed as a double, float, or long double, as appropriate for the return type of the function. If x is NaN, a NaN is returned. If x is +-Inf or +-0, x is returned. ATTRIBUTES
