Example
double y=6.23;
double x;
x=floor(y);
fmod
Computes the floating-point remainder of x / y . If the quotient of x / y cannot be represented,
the behavior is undefined.
Synopsis
#include
double fmod(double x, double y);
Returns
The value of x if y is zero. Otherwise, it returns the value f, which has the same sign as x,
such that x – i * y = f for some integer i, where the magnitude of f is less than the magni-
tude of y.
Example
double y=7.23;
double x=2.31;
double z;
z=fmod(y,x);
free
Causes the space pointed to by ptr to be deallocated, that is, made available for further
allocation. If ptr is a null pointer, no action occurs. Otherwise, if the argument does not
match a pointer earlier returned by the
calloc , malloc , or realloc function, or if the
space has been deallocated by a call to free or realloc , the behavior is undefined. If
freed space is referenced, the behavior is undefined.
Synopsis
#include
void free(void *ptr);
Example
char *buf;
buf=(char*) calloc(40, sizeof(char));
free(buf);
