TTCalc

TTCalc is an open source mathematical calculator. It features arithmetical
functions, trigonometric functions, inverse trigonometric functions,
hyperbolic functions, inverse hyperbolic functions, logical operators,
logarithms, functions for converting between degrees and radians and
so on. Additionally the program allows a user to define his own
variables and functions.

The program possesses an easy to use interface. Calculations are performed
by using binary floating point numbers with three kinds of precision,
the biggest has 864 bits for its mantissa and 128 bits for its exponent
that is about 6.70897699... * 10^51217599719369681875006054625051616609
with 258 valid decimal digits. TTCalc independently allows to insert and
display values with the base (radix) from two to sixteen.
