Vertical - Very Tiny Calculator
A pocket calculator
Vertical is a small calculator ; not by the size nor by the memory used, but actually by the features :) However the following ones are present :
double precision (ahem)
support of usual arithmetical operations and most common functions
support of parentheses
recognition (well, approximately) of implicit multiplications
exotic operators : existence of a division with lower priority, relative error, and others
recognition of pi and misc. physical constants
hierarchical abbreviations of function
history and (some day) access to previous results
possibility to visualize the RPN of the required computation
computations possible from the command line (thus usable by scripts)
quite compact (executable : ~29 ko compiled with -o2)
open source (GPL license)

The fact that this calculator got the same name as an alcoholic beverage is of course a mere coincidence.
If it isn't enough, you can have a look to
qalc
, which seems quite better.
As usual, critics, death threats, suggestions, etc, are welcome by e-mail.
