fmodl(long
double x, long double

fmod() function computes the floating-point
remainder of x/ y.
fmod(), fmodf(), and
fmodl() functions return the value
x- i*y, for some
integer i such that, if y is non-zero,
the result has the same sign as x and magnitude less
than the magnitude of y. If y is
zero, whether a domain error occurs or the fmod()
function returns zero is implementation-defined.
fmod() function conforms to ANSI
X3.159-1989 (“ANSI C89”).
