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 radix path's row floor; NEGATIVE restores the built-in.

Used in both directions. A huge value DECLINES the radix path, which is what keeps the introsort's and the counting path's own negative controls non-vacuous now that the floor sits below their fixture sizes. A small one drives ordinary fixtures through the radix path. Has no effect on the C++ engine.
