> NumberUtils fails to create requested type for floating point zero
> ------------------------------------------------------------------
>
> Key: LANG-1646
> URL: https://issues.apache.org/jira/browse/LANG-1646
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.math.*
> Affects Versions: 3.12.0
> Reporter: Alex Herbert
> Assignee: Alex Herbert
> Priority: Trivial
> Fix For: 3.12.1
>
>
> This currently fails:
> {code:java}
> assertEquals(Float.valueOf(0), NumberUtils.createNumber("0F"));
> assertEquals(Double.valueOf(0), NumberUtils.createNumber("0D"));
> {code}
> This passes:
> {code:java}
> assertEquals(Float.valueOf(0), NumberUtils.createNumber("0.F"));
> assertEquals(Double.valueOf(0), NumberUtils.createNumber("0.D"));
> assertEquals(Float.valueOf(0), NumberUtils.createNumber("0e0F"));
> assertEquals(Double.valueOf(0), NumberUtils.createNumber("0e0D"));
> {code}
> This is due to the incorrect extraction of the mantissa for a floating point
> value when there is no exponent or decimal place as it includes the trailing
> format specifier (F or D). The input string is then not detected as being all
> zeros and the returned type is BigDecimal.
