Functions
const std::vector< std::string > &	openswmm::mathexpr::function_names ()
	Return recognized built-in function names in stable token order.

int	openswmm::mathexpr::parse (const std::string &expr_str, Expression &result)
	Tokenize an infix expression and construct its postfix representation.

double	openswmm::mathexpr::evaluate (const Expression &expr, const std::function< double(const std::string &)> &var_lookup)
	Evaluate postfix tokens with a synchronous named-variable callback.

double	openswmm::mathexpr::evaluate (const Expression &expr, const double *vars, int n_vars)
	Evaluate using variable indices stored in a compiled expression.

int	openswmm::mathexpr::bind_variables (Expression &expr, const char const name_table, int n_vars)
	Bind each variable token to the first matching table entry.

int	openswmm::mathexpr::compute_max_stack_depth (const Expression &expr)
	Compute the peak operand-stack occupancy implied by postfix tokens.

double	openswmm::mathexpr::evaluate_fast (const Expression &expr, const double *vars) noexcept
	Evaluate the supported postfix subset with a fixed 32-value stack.
