Textual calculator You can enter an expression, and the calculator, well, will calculate it (that's quite normal I think) Trigonometry is in degrees. This project supports basics operations, trigonometry, and some logarithms. Complex numbers, booleans and variables are not supported. The project also features an error detector. Lexicon: + = addition - = subtraction * = multiplication / = division % = modulo ^ = exponent ln = natural logarithm log = common logarithm abs = absolute sin = sine cos = cosine tan = tangent asin = arcsine acos = arccosine atan = arctangent pi = pi e = Euler's number ans = last result Examples: 1+2*3 3*(1+2) 1/27 4*pi (1+sqrt(5))/2 exp(6)-(pi^4+pi^5) ln(64)/ln(2) ln(8+sqrt(1+8^2)) sin(48)/cos(48)
