Eric V. Smith added the comment: By using %s, you're asking the formatting code to first convert the parameter to a string. Then, by using .10, you're asking it to truncate the value.
It's essentially equivalent to: >>> str(-7.7176718e-05) '-7.7176718e-05' >>> str(-7.7176718e-05)[:10] '-7.7176718' and: >>> str(-0.0000771767) '-7.71767e-05' >>> str(-0.0000771767)[:10] '-7.71767e-' This isn't a bug. If you want more control over the formatting, use %f, %e, or %g: >>> '%.10f' % -7.7176718e-05 '-0.0000771767' ---------- nosy: +eric.smith resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23627> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
