Not R related at all. $ python Python 2.7.13 (default, Sep 26 2018, 18:42:22) [GCC 6.3.0 20170516] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> round((.575*100),0) 57.0 >>> round(57.5,0) 58.0 Same "issue". :) You'll need to dig into how numbers are floating numbers are represented in a finite set.
