INC_MANH

#define INC_MANH	(		u,

	)

Value:

do {                    \
    uint64_t o = u.bits.manh;               \
    u.bits.manh += (c);                 \
    if (u.bits.manh < o) {                  \
        u.bits.exp++;                   \
        u.bits.manh |= 1llu << (LDBL_MANH_SIZE - 1);    \
    }                           \
