formula_error

Defined in header: <ixion/exceptions.hpp>

class formula_error : public std::exception

Exception carrying a formula error value. The interpreter throws it while evaluating a formula, in which case the error value becomes the result of the formula cell, and the cell value accessors throw it when asked for a value the cell cannot provide, such as the numeric value of a formula cell in error or of a cell that has not been calculated yet.
