3# Tests for the :On variable modifier, which returns the words, sorted in
4# ascending numeric order.

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