Advanced Calculator (Expression)

Advanced Calculator (Expression-based) VARIABLES (case-insensitive): A, B, C, D, E - Optional inputs - Unconnected inputs default to 0 - Accepts INT / FLOAT / STRING (auto-cast) -------------------------------------------------- EXPRESSION RULES: - Multiline expressions supported - Newlines and extra whitespace are removed automatically - Variables and function names are case-insensitive -------------------------------------------------- AVAILABLE FUNCTIONS: Basic Math: ceil(x) : round up floor(x) : round down round(x) : round to nearest abs(x) : absolute value Min / Max: min(a, b, ...) max(a, b, ...) Power / Roots: pow(a, b) : a raised to power b sqrt(x) : square root Fractional: frac(x) : fractional part of x defined as x - floor(x) works correctly for negatives -------------------------------------------------- ERROR HANDLING: - Invalid expressions return 0 - Unconnected inputs are treated as 0 - Safe evaluation (no system or file access)
