Detailed Description

Find N-th value in array from insertion sort.

Finds out and returns the NORDth value in XVALT (ascending order). This subroutine uses insertion sort, limiting insertion to the first NORD values, and even less when one can know that the value that is considered will not be the NORDth. It uses only a work array of size NORD and is faster when NORD is very small (2-5), but worst case behavior can happen fairly probably (initially inverse sorted). In many cases, the refined quicksort method implemented by VALNTH / INDNTH is faster, though much more difficult to read and understand.

Parameters

[in]	integer(i4)/real(sp,dp), dimension(:) :: XVALT	Array to be ranked.
[in]	integer(i4) :: NORD	Number of ranked elements.

Return values

integer(i4)/real(sp,dp) :: FNDNTH

Value of NORDth rank.
