TTCalc



TTCalc is an open source bignum 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.
