Value:

s0 = ( *s << biH ) >> biH;          \
    s1 = ( *s >> biH ); s++;            \
    rx = s0 * b1; r0 = s0 * b0;         \
    ry = s1 * b0; r1 = s1 * b1;         \
    r1 += ( rx >> biH );                \
    r1 += ( ry >> biH );                \
    rx <<= biH; ry <<= biH;             \
    r0 += rx; r1 += (r0 < rx);          \
