^ special character when extended_glob alternative enabled in zsh. it's expanded before function called, there's no workaround possible inside function.

you can disable extended_glob altogether:

setopt no_extended_glob

or provide alias interactive use, expand noglob calc, preventing filename expansion:

alias calc='noglob calc'

shell zsh
