C++ (Cpp) f_lt_p Examples

Example #1

File: rational.c Project: alloy/mr-experimental

static VALUE
f_round_common(int argc, VALUE *argv, VALUE self, VALUE (*func)(VALUE, SEL))
{
    VALUE n, b, s;

    if (argc == 0)
	return (*func)(self, NULL);

    rb_scan_args(argc, argv, "01", &n);

    if (!k_integer_p(n))
	rb_raise(rb_eTypeError, "not an integer");

    b = f_expt(INT2FIX(10), n);
    s = f_mul(self, b);

    s = (*func)(s, NULL);

    s = f_div(f_rational_new_bang1(CLASS_OF(self), s), b);

    if (f_lt_p(n, ONE))
	s = f_to_i(s);

    return s;
}

Example #2

inline static long

{
    long q, r, fx;

    assert(!f_lt_p(x, ONE));

    q = (NUM2LONG(f_size(x)) - sizeof(long)) * 8 + 1;

    if (q > 0)
	x = f_rshift(x, LONG2NUM(q));

    fx = NUM2LONG(x);

    r = -1;
    while (fx) {
	fx >>= 1;
	r += 1;
    }

    return q + r;
