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

Errors

When called:
evaluation_error(Exception)

Examples

...,
Divisor =:= 0,
evaluation_error(zero_divisor).
