Other necks() questions.
Many of the math functions in Annex F in C17, have words like:
The returned values are exact and are independent of the current rounding direction mode.
Perhaps those should be added to necks().
Also, if long double is a pair of doubles, what is nextup(1.L)?
Is it
1.L + LDBL_EPSILON
or
1.L + LDBL_TRUE_MIN == 1.L + LDBL_EPSILON * LDBL_MIN
