Hello Jan,
what you are suggesting is not a backward compatible change.
There is a source compatibility impact, meaning that for some call
sites, the mapping of existing code using BigDecimal before and after
the addition of the overloaded method would change. That wouldn't
necessarily preclude us from making such a change (and such changes have
been made in the past), but extra caution and analysis would be called for.

If we add BigDecimal,valueOf(float), then a program recompiled with
the new JDK may change its behavior,
you can think that the new behavior is more "correct" that the current
one, but changing the behavior of existing programs is usually a big
NO ! in Java.
Also, I believe that the reason there is no such factory method that
takes a float is that doing computations on floats is not recommanded,
it becomes a mess rapidly of the imprecision of the float32
representation, .
For the same reason, in Java, 2.0 is a double and there is no
FloatStream while there is a DoubleStream.

Rémi
