Hi ElMaestro,

❝ Perhaps a little oddly, but in the C standard C will round down for integers

I see. Another hint that C is a child of Fortran (also rounding down).

❝ […] This is done e.g. by comparison with a true double precision figure like 80.00 rather than 80.

Yep. ~~In my future sim’s I will abandon rounding at all.~~ Edit: See above. In my sim’s I used the ratios (not percentages) rounded to 4 decimals.
round(x.xxxxx,4) works – the problem comes with round(xxx.xxx,2).
