Arithmetic in .ini and .hal files was created by frogandspanner
Rather than doing dynamic arithmetic in hal, which is suitable for variables, there are some constants that I'd like to do arithmetic on to become a constant to be a setp on a pin.

e.g. something like
MYCONSTANT=MAX_LINEAR_VELOCITY*25.4

Is this possible?

As far as I know this is not possible, would be a great improvement.

For now, I just write modified components for my Hal, which do have a param or pin to set for example the scale.

It is possible to use haltcl files
