is int(round(val)) safe?

[Russell E. Owen]

I realize this probably a stupid question, but...is it safe to 
round to the nearest integer by using int(round(val))?

I suspect it is fine, but wanted to be sure that weird floating point 
representation on some platform might make it unsafe there (i.e. get the 
wrong value due to the floating point value being an approximation) and 
if so, is there a Better Way).
