Tension Software today released Calcline 1.2, an application designed to evaluate mathematical expressions with parentheses, nested functions, and variables. The mathematical tool is developed in Objective-C and Cocoa exclusively for Mac systems as an easy to use tool that serves as a substitute for the "ancient and obsolete" desktop calculator. Variable assignment and reference inside expressions are simplified via an interactive table, and Calcline supports high precision calculations using long double values. The latest release features smart pasting, new math functions, a result copy button, a fast decimal precision popup, and the ability to update via the network. Calcline 1.2 is priced at $20, and requires Mac OS X 10.4 or later.
