> Key: LANG-1444
> URL: https://issues.apache.org/jira/browse/LANG-1444
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.math.*
> Affects Versions: 3.8.1
> Reporter: Costa Theodosiou
> Priority: Major
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> The following code demonstrates the issue:
> {{System.out.println(NumberUtils.createNumber("1.1").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.00001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.0000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.000000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.00000000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.0000000000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.000000000000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.00000000000000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.0000000000000000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.000000000000000000001").getClass().getName());}}
> {{System.out.println(NumberUtils.createNumber("1.00000000000000000000001").getClass().getName());}}
> will print:
> {{java.lang.Float}}
> {{java.lang.Float}}
> {{java.lang.Float}}
> {{java.lang.Float}}
> {{java.lang.Double}}
> {{java.lang.Double}}
> {{java.lang.Double}}
> {{java.lang.Double}}
> {{java.lang.Float}}
> {{java.lang.Float}}
> {{java.lang.Float}}
> {{java.lang.Float}}
> It seems the problem is towards the bottom of the createNumber method that
> compares the float to double string representation:
> f.toString().equals(d.toString())
> For the misbehaving tests, the string "1.0".equals("1.0")
