macOS New App Release – TS Calc 1.6


Product Announcement – Tension Software of Milano, Italy has released TS Calc 1.6, their Mac app designed to solve mathematical models. TS Calc is a document based application and its documents can be realized and used as calculation models for a specific mathematical technical problems. It is a complete different approach to solve problems then spreadsheets.

A TS Calc document contains a series of equations and a list of variables and constants used by the equations. When the document is set-up, the user can insert the input value and see the output generated by the TS Calc document using the equations to solve the problem.

TS Calc uses a math calculation engine entirely developed and coded internally by Tension Software in C and Objective-C, able to solve equations with any nested level of parenthesis, variables and a large type of mathematical functions at an impressive speed, almost Instantaneously on a modern Mac.

All the variables and constants used by the functions are automatically recognized and inserted inside dedicated tables. Selecting any function shows all the variables and constant used in the info panel
Selecting any variables or constant show to functions using it. TS Calc solves the equations from a numerical point of view as-you-type, the user has just to enter inside the table the input values and the output is instantly calculated
