0.5 is one of the values that can always be represented exactly. The
fractional part of IEEE 754 floating point numbers is represented as
sums of negative powers of 2, i.e. 0.5, 0.25, etc.
It should have been "x.5" instead of "0.5" :)
What's your opinion regarding the point that the compiler does not
handle the rounding mode when "Round" is inlined for constants?
