<h1>TTCalc</h1>
<p>
TTCalc is a mathematical calculator. It 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
program possess trigonometric functions, inverse trigonometric functions, hyperbolic
functions, logical operators, logarithms, functions for converting between degrees and
radians and so on. Additionally the program 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. The program independently allows to insert and display values with
the base (radix) from two to sixteen.
