Curiously, on core-updates, ceiling/ is inconsistent with ceiling-quotient
and ceiling-remainder:

scheme@(guile-user) [1]> (ceiling/ 130.0 -10/7)
$28 = -90.0
$29 = 1.4285714285714257
scheme@(guile-user) [1]> (ceiling-quotient 130.0 -10/7)
$30 = -91.0
scheme@(guile-user) [1]> (ceiling-remainder 130.0 -10/7)
$31 = 0.0

But on 'master', the results are consistent:

scheme@(guile-user)> (ceiling/ 130.0 -10/7)
$1 = -91.0
$2 = 0.0
scheme@(guile-user)> (ceiling-quotient 130.0 -10/7)
$3 = -91.0
scheme@(guile-user)> (ceiling-remainder 130.0 -10/7)
$4 = 0.0

To be investigated ...

Greetings,
Maxime.
