#scalc - Simple calculator

scalc is a very simple stack-based calculator that aims to be small.

#Basic usage

scalc presents the user with an interactive prompt. Operations are written in Reverse Polish Notation and values are stored in a stack. Supported operations include basic arithmetics, logarithms, trignometry, etc. scalc also supports commands that modify the behavior of the stack and scalc itself.

$ ./scalc
> 1 2 +
3.000000000
> 4
4.000000000

7.000000000
> 2 / 18 +
