Arguments

Type IntentOptional Attributes Name
integer(kind=int64), intent(in) :: n

forced floor, or a negative value to restore.

Description

Test-only override for the TAIL passes' row floor; NEGATIVE restores the built-in.

Separate from the sort's own floor because the tail is memcpy-shaped and crosses over an order of magnitude lower; the two shared one setting until this existed, which meant one number governing two different questions. Has no effect on the C++ engine.
