Is there a definition on the "/.zcalcrc file syntax?
For example how does one put in the -f (use floating point calculations) into it.
Also possible add constants that I frequently use in zcalc only, etc.
Thanks

It's just normal shell code.
One point worthy of note is that it's within an "emulate -L zsh", so you can put in any option settings that will only apply within the function. You can add stuff like
float myfloat=3.19824
Each line in zcalc is evaluated separately as a $(( ... )) expression --- so it determines
each time if each value is a floating point or integer. For floating point just make sure there
are decimal points on the numbers. But if you want you can
setopt force_float
in the initialisation file.
