[Feature]: Calculator in the chat Mod

[Ercument5038]

Suggestion

I often find myself doing stacks into items calcs. But it sucks to always open or switch to the calculator app.

I tried adding this mod https://modrinth.com/mod/calcmod in and it worked fine.

I second this, I literally play with a calculator next to me in person to deal with fluid conversions. An idea could be to readd the crafting calculator mod from nomi. As much as the EMI tree is substantially better, it can be shift right-clicked to turn into a normal +-*/ operation calculator which I used substantially in nomi.
