Tension Software has updated Calcine
(http://pomola.com/products_calcline/calcline.html), its US$20
desktop calculator for Mac OS X 10.5 (“Leopard), to version 2.0. The
new version sports a redesigned interface with a new layout.

It also sports an improved variables table and a new Calc Log draw
area. Plus, there are bug fixes.

Calcine evaluates mathematical expressions with parentheses, nesteds
function and variables. It can work as a small strip window providing
an area to input and solve mathematical expressions or as a full size
window application using variables and a full report of executed
calculations solved step by step.
