built-in method
evaluation_error/1
Description
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
Modes and number of proofs
evaluation_error(@nonvar) - error
