DIV/MOD only. - CHR returns an owning one-byte STRING, not CHAR; CHR(0) retains one NUL byte. - STR_TO_NUM always returns REAL and shares parseNumber (strtod, full consumption, overflow rejected) with IS_NUM. - - NUM_TO_STR uses std::to_string, preserving the full signed i64 range and six - fractional digits for REAL. + - NUM_TO_STR keeps the full signed i64 range for INTEGER; REAL uses the shortest + round-trip text (realText in string.cc), byte-identical to OUTPUT's IR helper in + OutputGen.cc (`__cps_output_real`); change both together. C_DOUBLE output keeps `%f`. - **`getExprTypeInfo` returns nullptr** for expressions it can't classify (null-check it at any new call site) and internally defaults to INTEGER for unclassified arithmetic expressions; unknown or unmatched calls diagnose and return nullptr. |
