3# Tests for the variable modifiers ':On', which returns the words, sorted in
4# ascending numeric order, and for ':Orn' and ':Onr', which additionally
5# reverse the order.
6#
7# The variable modifiers ':On', ':Onr' and ':Orn' were added in var.c 1.939
8# from 2021-07-30.

10# This list contains only 32-bit numbers since the make code needs to conform
11# to C90, which does not provide integer types larger than 32 bit.  It uses
12# 'long long' by default, but that type is overridable if necessary to support
13# older environments.
14#
15# To get 53-bit integers even in C90, it would be possible to switch to
16# 'double' instead, but that would allow floating-point numbers as well, which
17# is out of scope for this variable modifier.
