Let's imagine youre crafting an item A that requires 100 x, 100 y and 100 z. You know the starting CT quality, you know how it will degrade in process (linear way, that's it), you want to build, says, 20 pieces. Crafting window making all the precalcs and shows you, says, you need 2025 of x, 2025 of y, and 2025 of z. You're clicking start button, going to sleep happy, then wake up next day and voila! crafting has stopped after 19 cycles cuz you don't have enough materials. You're looking at the numbers and realize that 1-2 of each material are missing now.

FFS fix the goddamn rounding in a way that it shows EXACT, FINE amount of materials I require.
