JCalculator

A simple command-line Java calculator program. Features basic arithmetic and trigonometric functions. Runs using a Pratt-like parsing algorithm. Not very complicated at the moment, but I hope to add more features and accurate calculating.

Feature List:

• Basic arithmetic: addition, subtraction, multiplication, and division.
• Square roots.
• Exponents.
• Absolute value.
• Trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent, as well as their ^-1 versions.
• Simple parenthesis to force evaluation of certain parts.
• Implicit multiplication.
• Variables (not fully compatible with implicit multiplication).
