TTCalc is a mathematical calculator that features a well structured graphical interface and is very easy to use.

TTCal is composed of a standard scientific calculator and variable, functions, precision and display configuration tabs.

The program has a nice user interface, formulas for calculating can be inserted by using a keyboard or a mouse, the result is automatically shown in a second window without using any additional keys such as 'equal'.

The application possesses trigonometric functions, inverse trigonometric functions, hyperbolic functions, logical operators, logarithms, functions for converting between degrees and radians and so on. Additionally, TTCalc allows the user to define his own variables and functions.

Calculations are performed by using floating point numbers with three kind of precision, the biggest has 288 bits for its mantissa and 96 bits for its exponent that is about 2.551...e+11925026709067095507636213441 with 85 valid decimal digits.

TTCalc independently allows to insert and display values with the base (radix) from two to sixteen.

What's New in This Release: [ read full changelog ]

· added: German translation

· added: on display tab: an option how many digits should be grouped
· changed: the way how buttons on display tab work
· suppose we have "123+34+56" in the first edit, then select (by mouse or a keyboard) "123+34" similar as you would like to copy them to the clipboard, then press a button let we say "sin" - the result is: "sin(123+34)+56"
· updated: Chinese translation
· fixed: ttcalc didn't correctly delete variables/functions from its config file so when you restarted the program you still had the deleted variables/functions
· fixed: option: "parameters separated by" was not correctly read from the config file
