Inputs

error

a floating-point error object from the Factor VM

Outputs

exceptions

a sequence of fp-exceptions

Word description
When a floating-point trap is raised, the Factor VM reports the trap by throwing a Factor exception containing the exception flags at the time the trap was raised. This word extracts the exception flag information from error and converts it into a sequence of fp-exceptions.
