Dc (RPN) or bc (infix) are the way to go for non-trivial scripted
calculation. They do floating point, arbitrary precision and have
formatted printing. (BASH has this, too, perhaps even better, being
modelled after the C library printf() function.)

Really..

Yes, really.


Have had a quick look at bc from command line to check on something I
noticed some time ago, it returns the output of 7.3/2 as 3 for
example, a little rounding problem methinks.... as ideally a better
answer could be 4 if it was giving a rounded int rather than a
truncated int ... not a lot better than bash really... accepting
floating point is only useful if the appropriate value is returned...

Your look was too quick. The precision is arbitrary and programmable and
the default precision is 0 (integers).


As I said for anything beyond the really simple one would need to
work on it ...

Anything beyond the really simple requires work no matter what.


...

RPN .... my idea of torture by arithmetic... :-)

Parentheses are the real torture.
