Moreover, it will be less than 1.0 if and only - * if X < Y. In that case, it will have to be shifted left one bit to - * become a normal number, and the exponent decremented. Thus, the - * desired exponent is: - * - * left_shift = x->fp_mant < y->fp_mant; - * result_exp = x->fp_exp - y->fp_exp - left_shift; - * - * The quotient mantissa X/Y can then be computed one bit at a time - * using the following algorithm: - * - * Q = 0; -- Initial quotient. - * R = X; -- Initial remainder, - * if (left_shift) -- but fixed up in advance. - * R *= 2; - * for (bit = FP_NMANT; --bit >= 0; R *= 2) { - * if (R >= Y) { - * Q |= 1 << bit; - * R -= Y; - * } - * } - * - * The subtraction R -= Y always removes the uppermost bit from R (and - * can sometimes remove additional lower-order 1 bits); this proof is - * left to the reader. - * - * This loop correctly calculates the guard and round bits since they are - * included in the expanded internal representation. The sticky bit - * is to be set if and only if any other bits beyond guard and round - * would be set. From the above it is obvious that this is true if and - * only if the remainder R is nonzero when the loop terminates. - * - * Examining the loop above, we can see that the quotient Q is built - * one bit at a time ``from the top down''. This means that we can - * dispense with the multi-word arithmetic and just build it one word - * at a time, writing each result word when it is done. - * - * Furthermore, since X and Y are both in [1.0,2.0), we know that, - * initially, R >= Y. (Recall that, if X < Y, R is set to X * 2 and - * is therefore at in [2.0,4.0).) Thus Q is sure to have bit FP_NMANT-1 - * set, and R can be set initially to either X - Y (when X >= Y) or - * 2X - Y (when X < Y). In addition, comparing R and Y is difficult, - * so we will simply calculate R - Y and see if that underflows. - * This leads to the following revised version of the algorithm: - * - * R = X; - * bit = FP_1; - * D = R - Y; - * if (D >= 0) { - * result_exp = x->fp_exp - y->fp_exp; - * R = D; - * q = bit; - * bit >>= 1; - * } else { - * result_exp = x->fp_exp - y->fp_exp - 1; - * q = 0; - * } - * R <<= 1; - * do { - * D = R - Y; - * if (D >= 0) { - * q |= bit; - * R = D; - * } - * R <<= 1; - * } while ((bit >>= 1) != 0); - * Q[0] = q; - * for (i = 1; i < 4; i++) { - * q = 0, bit = 1 << 31; - * do { - * D = R - Y; - * if (D >= 0) { - * q |= bit; - * R = D; - * } - * R <<= 1; - * } while ((bit >>= 1) != 0); - * Q[i] = q; - * } - * - * This can be refined just a bit further by moving the `R <<= 1' - * calculations to the front of the do-loops and eliding the first one. - * The process can be terminated immediately whenever R becomes 0, but - * this is relatively rare, and we do not bother. - */ - -struct fpn * -__fpu_div(fe) - struct fpemu *fe; -{ - struct fpn *x = &fe->fe_f1, *y = &fe->fe_f2; - u_int q, bit; - u_int r0, r1, r2, r3, d0, d1, d2, d3, y0, y1, y2, y3; - FPU_DECL_CARRY - - /* - * Since divide is not commutative, we cannot just use ORDER. - * Check either operand for NaN first; if there is at least one, - * order the signalling one (if only one) onto the right, then - * return it.

The exponent of sqrt(x) is either exp/2 or (exp-1)/2 - * as above. This leaves us with the problem of finding the square root - * of a fixed-point number in the range [1..4). - * - * Though it may not be instantly obvious, the following square root - * algorithm works for any integer x of an even number of bits, provided - * that no overflows occur: - * - * let q = 0 - * for k = NBITS-1 to 0 step -1 do -- for each digit in the answer... - * x *= 2 -- multiply by radix, for next digit - * if x >= 2q + 2^k then -- if adding 2^k does not - * x -= 2q + 2^k -- exceed the correct root, - * q += 2^k -- add 2^k and adjust x - * fi - * done - * sqrt = q / 2^(NBITS/2) -- (and any remainder is in x) - * - * If NBITS is odd (so that k is initially even), we can just add another - * zero bit at the top of x. Doing so means that q is not going to acquire - * a 1 bit in the first trip around the loop (since x0 < 2^NBITS). If the - * final value in x is not needed, or can be off by a factor of 2, this is - * equivalant to moving the `x *= 2' step to the bottom of the loop: - * - * for k = NBITS-1 to 0 step -1 do if ... fi; x *= 2; done - * - * and the result q will then be sqrt(x0) * 2^floor(NBITS / 2). - * (Since the algorithm is destructive on x, we will call x's initial - * value, for which q is some power of two times its square root, x0.) - * - * If we insert a loop invariant y = 2q, we can then rewrite this using - * C notation as: - * - * q = y = 0; x = x0; - * for (k = NBITS; --k >= 0;) { - * #if (NBITS is even) - * x *= 2; - * #endif - * t = y + (1 << k); - * if (x >= t) { - * x -= t; - * q += 1 << k; - * y += 1 << (k + 1); - * } - * #if (NBITS is odd) - * x *= 2; - * #endif - * } - * - * If x0 is fixed point, rather than an integer, we can simply alter the - * scale factor between q and sqrt(x0). As it happens, we can easily arrange - * for the scale factor to be 2**0 or 1, so that sqrt(x0) == q. - * - * In our case, however, x0 (and therefore x, y, q, and t) are multiword - * integers, which adds some complication. But note that q is built one - * bit at a time, from the top down, and is not used itself in the loop - * (we use 2q as held in y instead). This means we can build our answer - * in an integer, one word at a time, which saves a bit of work. Also, - * since 1 << k is always a `new' bit in q, 1 << k and 1 << (k+1) are - * `new' bits in y and we can set them with an `or' operation rather than - * a full-blown multiword add. - * - * We are almost done, except for one snag.

(The relation only - * fails temporarily while y and q are being updated.) Since q < 2, y < 4. - * The sum in t can, in our case, be as much as y+(1<<1) = y+2 < 6, and. - * Furthermore, we can prove with a bit of work that x never exceeds y by - * more than 2, so that even after doubling, 0 <= x < 8. (This is left as - * an exercise to the reader, mostly because I have become tired of working - * on this comment.) - * - * If our floating point mantissas (which are of the form 1.frac) occupy - * B+1 bits, our largest intermediary needs at most B+3 bits, or two extra. - * In fact, we want even one more bit (for a carry, to avoid compares), or - * three extra.
