For q = rnd(u / v), in the case where + vprec <= qprec, an integer division with (about) qprec + vprec bits + for the dividend and the full divisor (i.e. vprec bits exactly) could + be used. This was the case in the past and was changed (due to a full + rewrite) on 2004-12-24 in rev 3161. + Potential bugs: * Possible integer overflows on some machines. |
