Loic Guibert commented on LANG-1187:
------------------------------------
I just take a quick look and it's seem to be caused by the order of conversion
priority for decimal number (Float > Double > BigDecimal) and the test for
select between those types is based on the number of digits past the decimal
point.
But wouldn't it be on significant digits instead ? (if significant digits >=7
there is a risk that float can be unable to represents the entire number)
> Method createNumber from NumberUtils doesn't work for floating point numbers
> other than Float
