[issue39749] python 3.8.1 (3.14 * 10 = 31.400000002 bug)

Steven D'Aprano added the comment: This behaviour is shared by all programming languages that use floating point numbers. For example, this is Ruby: [steve@ando ~]$ irb irb(main):001:0> 10 * 3.14 == 31.4 => false irb(main):002:0> 10 * 3.14 - 31.4 => 3.5527136788005e-15
