built-in method
.. index:: pair: evaluation_error/1; Built-in method .. _methods_evaluation_error_1:
::
evaluation_error(Error)
Throws an evaluation error. Used when evaluating an arithmetic expression generates an exception. This built-in method is declared private and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of goals:
::
...,
context(Context)
,
throw(error(evaluation_error(Error), Context))
.
This allows the user to generate errors in the same format used by the runtime.
Possible values for Error
include:
float_overflow
int_overflow
undefined
underflow
zero_divisor
::
evaluation_error(@nonvar)
- error
| When called:
| evaluation_error(Exception)
::
...,
Divisor =:= 0,
evaluation_error(zero_divisor)
.
