[issue34358] round() combined with product outputs ugly result

New submission from Sandu : `from scipy import stats` `a = stats.norm.cdf(2.1882658846227234)` `round(a,4)` gives: `0.9857` `round(a,4)*100` one would expect to output 98.57. It returns: `98.570001` For comparison, if I multiply with 10 or 1000 the output is as expected. --
