[Octave-bug-tracker] [bug #36121] num2str(2.4e9, 15) gives incorrect result

[Sebastian Held]

Follow-up Comment #2, bug #36121 (project octave):

My octave 3.2.4 on Ubuntu Precise (and Natty, both 32bit) does also not show
this problem, but on my 64bit gentoo box this happens:

octave:1> version
ans = 3.6.1
octave:2> sprintf('%d',double(intmax))
ans = 2147483647
octave:3> sprintf('%d',double(intmax)+1)
ans = -2147483648


But I have reports from two other people seeing this problem (see thread at
http://openems.de/forum/viewtopic.php?f=2&t=24&p=146#p146 )

May it be possible that this only shows up on 64 bit systems?

By the way:

octave:1> which num2str
`num2str' is a function from the file
/usr/share/octave/3.6.1/m/general/num2str.m
