@const MPMathKitErrorDomain
|

@brief Predefined error domain for errors from the MathKit framework.
|
|
|
|
@discussion Errors in MathKit can occur during parsing of expressions or
|
|
during evaluation of expressions. These two can be distinguished
|
|
by the error code. Parsing errors have lower error codes.
|
|
Evaluation errors (math errors) have error codes from @c 100 upwards.
