Even the IRS lets you round up?

put 2M trit in your orca's cargo hold and 4M in your corp hanger. drag to fill your cargo hold, it suggests moving 1,750,000. move 1,7499,999 instead, leaving 0.1 m^3 and two stacks. Try to drag 1 more trit over, and it tells you there's no room. stack the ore in your cargo hold, and you magically you have 0.1 free again.

i was using S projectile ammo (0.25m3) and minerals in multiple stacks for my tests, and it was working on dev.
will test again and report

trit would be best to test it as it has the smallest m3 if i recall, if that works everything else should
