Description
TCalc implements a minimal desktop calculator that in addition to floating point numbers recognises durations in hh:min:sec format and converts them to seconds. This can simplify time-based calculations. This command-line application provides command-line editing and history. Command math functions line sin or exp are available.

TCalc
This is a minimal desktop calculator (taken from the Lex/Yacc section of the OCaml manual) that can parse 3:04.5 as a time and covert it into 184.5 seconds. I'm using it for simple time calculations.
$ tcalc
3:04.5
184.50 (00:03:04.50)
11:52.2 / 2670 * 500
133.37 (00:02:13.37)
$
Operators: + - * / ^
Common math functions like
sin,log,expCommand line editing and history
Variables (x = 21 * 2)
Tab completion for functions
To help with debugging the parser, the parsed expression is emitted in prefix syntax.
Installation via Opam
Opam is the OCaml package manager that installs packages by compiling them from source code.
