pcalc is a programmer's calculator. It simplifies some operations
(especially working with multiple bases) that are hard work without
this or another programmer's calculator. Main features:
o Full math parser, parentheses, add, sub, mult, div, exponential
o Automatic conversion between HEX DEC OCT BIN numbers
o Mixing different bases in one expression
o Definable variables
o Math constants (E PI ...)
o Built in math functions (sin/cos/sqrt ...)
math/pari updates (Math::Pari still gets updated but even recently
released versions require old Pari; the crypto libs based on this
seem a bit unloved these days).

GNU PSPP is a program for statistical analysis of sampled data. It is a
free as in freedom replacement for the proprietary program SPSS, and
appears very similar to it with a few exceptions.
The most important of these exceptions are, that there are no "time
bombs"; your copy of PSPP will not "expire" or deliberately stop working
in the future. Neither are there any artificial limits on the number of
cases or variables which you can use. There are no additional packages
to purchase in order to get "advanced" functions; all functionality that
PSPP currently supports is in the core package.
PSPP is a stable and reliable application. It can perform descriptive
statistics, T-tests, anova, linear and logistic regression, measures of
association, cluster analysis, reliability and factor analysis,
non-parametric tests and more. Its backend is designed to perform its
analyses as fast as possible, regardless of the size of the input data.
You can use PSPP with its graphical interface or the more traditional
syntax commands.

GNU Spread Sheet Widget is a library for Gtk+ which provides a widget
for viewing and manipulating 2 dimensional tabular data in a manner
similar to many popular spread sheet programs.
The design follows the model-view-controller paradigm and is of
complexity O(1) in both time and space. This means that it is efficient
and fast even for very large data.
Features commonly found in graphical user interfaces such as cut and
paste, drag and drop and row/column labelling are also included.

bcal (Byte CALculator) is a REPL CLI utility for storage expressions,
unit conversions or address calculations. If you can't calculate the hex
address offset for (512 - 16) MiB, or the value when the 43rd bit of a
64-bit address is set mentally, bcal is for you.
It has a bc mode for general-purpose numerical calculations.
Features:
* evaluate arithmetic expressions involving storage units
* perform general purpose calculations (using bc)
* convert to IEC/SI standard data storage units
* interactive mode with the last valid result stored for reuse
* show the address in bytes
* show address as LBA:OFFSET
* convert CHS to LBA and vice versa
* base conversion to binary, decimal and hex
* custom sector size, max heads/cylinder and max sectors/track
some existing COMPILER lines with arch restrictions etc. In the usual
case this is now using "COMPILER = base-clang ports-gcc base-gcc" on
ports with c++ libraries in WANTLIB.
This is basically intended to be a noop on architectures using clang
as the system compiler, but help with other architectures where we
currently have many ports knocked out due to building with an unsuitable
compiler -
- some ports require c++11/newer so the GCC version in base that is used
on these archirtectures is too old.
- some ports have conflicts where an executable is built with one compiler
(e.g. gcc from base) but a library dependency is built with a different
one (e.g. gcc from ports), resulted in mixing incompatible libraries in the
same address space.
devel/gmp is intentionally skipped as it's on the path to building gcc -
the c++ library there is unused in ports (and not built by default upstream)
so intending to disable building gmpcxx in a future commit.
that aims to provide fast, extensible implementations of cutting-edge
machine learning algorithms.
Comes with command-line programs and python bindings

bc is an arbitrary precision calculator language. Syntax is similar to
C, but differs in many substantial areas. It supports interactive
execution of statements.
It can also be used as a simple console-based calculator.
This GNU version of bc contains several extensions beyond traditional bc
implementations and the POSIX draft standard.
This package includes GNU dc, another arbitrary precision calculator.
dc is a reverse-polish desk calculator which supports unlimited
precision arithmetic. It also allows you to define and call macros.
using GMP as backend. This is needed by frama-c because num was removed
from the OCaml compiler distribution.
Marked as BROKEN till the next OCaml upgrade.
