after for several years using my self-built octave-3.6.4 I finally
switched to octave-4.4.2 distributed with Ubuntu-18.04.
And I've noticed that *printf functions work wrongly with %u format:
octave:3> printf("%u\n", 1234567.890123456)
octave:4> sprintf("%u\n", 1234567.890123456)
ans = 1.23457e+06
ans = 4.2.2
%u format is supposed to output without decimal period and exponent. In
this particular case I expect output like this (the same machine and OS) :
address@hidden:~$ perl -e 'printf("%07u\n", 1234567.890123456)'
Am I missing something or it's a bug ? And if it's a bug, will using
'floor', like here:
octave:8> sprintf("%u\n", floor(1234567.890123456))
ans = 1234567
be a reliable workaround ?
This seems to be a bug that is still there in octave 5.1.1--
