Suggestion: basic quick calculator

[Catchears]

Only had the game for a few days and loving it, but I often find myself reaching for a calculator to find out exactly how many machines I need.
In Satisfactory, you can press N to open a text search that can either search or be used as a quick calculator (+-*/^()). I can just press N and type 35/2.4 and instantly know how many machines I need to build.
External calculators aren't bad, but an easily accessible ingame one would be amazing.
