The current code claims to do that. But once you look at the code you see
that it truncates instead:
static inline depth_t gas_mod(struct gasmix *mix, pressure_t po2_limit, int
roundto) {
depth_t depth;
depth.mm = ((po2_limit.mbar * 1000 / get_o2(mix) * 10 - 10000) /
roundto) * roundto;
return depth;
}
So all we need to do is adjust this function to add (roundto - 1) to the
enumerator before deviding by roundto, correct?
