Calculator inside of vim.

Real calculator inside vim. It supports arbitrary complex arithmetics, expressions, variables, logic statements and loops.

Some examples:

> 5+4
9.0
> 7 * sqrt(4)
14.0

• vim 8.1 (for buftype=prompt)
• with +float
• with +channel

I recommend using Vim's native package management functionality: simply run following commands:

mkdir -p ~/.vim/pack/bundle/start
cd ~/.vim/pack/bundle/start
git clone https://github.com/fedorenchik/calculator.vim.git
vim -c 'helptags ALL' -c 'q'

Otherwise use your favourite package manager for Vim.
