Which in reality, is kinda odd. (Couldn't resist).

In reality, you could well be correct !!!
When I was involved in recruiting a C programmer ages ago, we set a
simple competence test. I lifted a snippet of code from one of OUR OWN
programs somewhere that said something like ...
real rr = our value of interest;
int ii = rr*10;
int mm = ( rr - (float(ii)/10) ) * 10;
if (mm>5)
float rr2 = int( rr + .5 );
else
float rr2 = int( rr);
We asked the candidates to identify what this code was doing, and could
they do it any simpler. We made a point of saying that all we wanted was
for them to spot what was going on ...
With only ONE exception, every candidate rewrote it and made it even
more convoluted. That one exception got it right ...
rr2 = round( rr);
Cheers,
Wol
