    mep4j

    Math Expression Parser 4 Java

    ...The library manages the 5 operators (+, -, /, %, *) together with the following functions: - "abs" - "cos" - "sin" - "acos" - "asin" - "cosh" - "sinh" - "tan", - "tanh" - "atan" - "sqrt" - "cbrt" - "root" - "log" - "log10" - "log1p" - "exp" - "expm1" - "atan2" - "pow" The library supports variables (case insensitive), custom and pre-loaded ("e" and "pi"). Example: int num_variations = 100; int init_value = 10; MathParser mathParser = new MathParser(); mathParser.putVariable("x", init_value); mathParser.parse("2 + (7 - 5) * 3.14159 * pow(x, (12-10)) + sin(-3.141)"); for(int i = init_value; i < num_variations; ++i) { Double result = mathParser.execute(); mathParser.putVariable("x", i); }
