u068928@mfnppb104:~> /apps/perl/5.8.8/bin/perl -e 'use Number::Format
qw(:subs); print format_number(97, 20), "\n";'
96
I believe it goes wrong in round(), which converts 97 to 96.99999...., and
then format_number() uses int() on the result giving the problem:
u068928@mfnppb104:~> /apps/perl/5.8.8/bin/perl -e 'use Number::Format
qw(:subs); printf("%.25f\n", 97);'
97.0000000000000000000000000
u068928@mfnppb104:~> /apps/perl/5.8.8/bin/perl -e 'use Number::Format
qw(:subs); printf("%.25f\n", round(97,20));'
96.9999999999999857891452848
Thanks,
