Hi
I reproduce your bug using "PostgreSQL 9.3.6, compiled by Visual C++ build
1600, 64-bit" on Windows 8
I also notice that SELECT floor(4.725 * power(10, 2)::numeric + 0.5) work as
expected
I don't think this is a bug -- just peculiarities of floating point math.

I think also that it is a float precision issue but the weird thing is
that both calls without floor return 273. Maybe the display method make
a rounding ?
SELECT 4.725 * power(10, 2)::numeric + 0.5) => 273.000
SELECT (4.725 * power(10, 2) + 0.5) => 273
