This is a simple calculator written in Rust.
It is an alternative to printf for shell command.
```.sh $ fmtcalc 4+2 6
$ fmtcalc "1+23 = {}" "1+23" 1+2*3 = 7
$ fmtcalc "0xFF - 654.321" -399.321
$ fmtcalc "3²+4²={}, 5²={}" "33+44" "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'
.sh
$ cargo install fmtcalc
