Copy full snippet

namespace Optimus {     namespace Expression     {         enum EParseFlags         &123;             Default              = 0,             ValidateConstants    = 1 << 0,         &125;     } }

Values

Remarks

Simple, fast expression evaluation engine. Can evaluate simple arithmetic expressions, including user-settable constants. 1 + 1 foo + (3 * bar)

Allowable operands are taken from Python and are currently as follow: -x Unary negation x + y Addition x - y Subtraction x * y Multiplication x / y Division (div-by-zero returns zero) x ** y Raise x to y's power

Terms can also be grouped by parentheses '(' and ')'.

Constants that begin with a number, include spaces or any of the above operands/parentheses are allowed, but must be then enclosed in single quotes when referenced. E.g: 'foo(1)' * 2 rather than: foo (1) * 2
