@PauloCereda So far I've only done +,-,*,/,(,),ln, and parsing (plus unpacking registers when necessary). I still have trigonometric functions (sin,cos,tan,cot,tan2), hyperbolics (sinh, cosh, tanh, coth), arc-trigo (asin,acos,atan,acot), arc-hyperbolics (asinh,acosh,atanh,acoth), exponentials (exp,pow,sqrt), comparisons (<,>,=,?,min(x,y,z,...),max(x,y,z,...),abs(x),sign(x)), conversions (from binary, hexadecimal,...), misc (Gamma function, hypergeometric functions, the Meilin G function... [joking])
