[ahorek (Pavel Rosický)]

is it a bug?

'%0.0f%' % 45

expected
ruby 2.4.1 =>  '45%'

actual
ruby trunk => ArgumentError: incomplete format specifier

workaround

'%0.0f%s' % [45, '%']
=> '45%'

ruby -v
ruby 2.5.0dev (2017-07-21 trunk 59380) [x86_64-linux]

No, it's not a bug. Use "%0.0f%%" (double %) instead.
