This is a simple calculator written in Rust.  
It is an alternative to printf for shell command.  

## Examples

```.sh
$ fmtcalc 4+2
6

$ fmtcalc "1+2*3 = {}" "1+2*3"
1+2*3 = 7

$ fmtcalc "0xFF - 654.321"
-399.321

$ fmtcalc "3²+4²={}, 5²={}" "3*3+4*4" "5*5"
3² +4² =25, 5² =25
```

For better ergonomics I often abbreviate `fmtcalc` as `println` in your shell startup files:

```.sh
alias println='fmtcalc'
```

## Installation

```.sh
$ cargo install fmtcalc
```
