ProbeLabs36 findings · 123 requirementsWhen ParseInt receives an integer token whose magnitude exceeds the supported int64 range, the parser shall return the documented overflow error.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When ParseInt receives an integer token whose magnitude exceeds the supported int64 range, the parser shall return the documented overflow error.
the parser shall always satisfy !raw_int_token_overflows_int64 | returns_parseint_overflow_error
Rationale & tags
Why this requirement exists, and how it is categorised.
Rationale & tags
Why this requirement exists, and how it is categorised.
Overflow is an externally visible ParseInt outcome and should be specified independently from valid integer parsing and malformed-token rejection.
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).
