**C++ Coders & Programmers
Here are the few functions this calculator performs.
•It performs the conversion from decimal to (Binary, Octal and Hex decimal) values.
•Calculates Sign, Tangant and Sec, Coses, Cot.
•Log, Antilog, Exponent, power values.
•Also it can store numbers in memory, find the square root of any number.
