#!./perl

# Tests sprintf, excluding handling of 64-bit integers or long
# doubles (if supported), of machine-specific short and long
# integers, machine-specific floating point exceptions (infinity,
# not-a-number ...), of the effects of locale, and of features
# specific to multi-byte characters (under use utf8 and such).

# In each of the the following lines, there are three required fields:
# printf template, data to be formatted (as a Perl expression), and
# expected result of formatting.  An optional fourth field can contain
# a comment.  Each field is delimited by a starting '>' and a
# finishing '<'; any whitespace outside these start and end marks is
# not part of the field.  If formatting requires more than one data
# item (for example, if variable field widths are used), the Perl data
# expression should return a reference to an array having the requisite
# number of elements.  Even so, subterfuge is sometimes required: see
# tests for %n and %p.

# The following tests are not currently run, for the reasons stated:
