round(50.5) = 50

Hello!

# SELECT round(5.5::float4),round(50.5::float4);
round | round
-------+-------
6 | 50
(1 row)

I think this is a bug, since I would expect 6 and 51. Doing the same
without the float4-cast, it works correct. This bug bites me while
passing parameters to a plpgsql function.

This happens both with Debian 7.3.4-9 and 7.4.1-3

Is this a real bug or am I missing something? A bug fix or work-around
would be nice.

BYtE
