STRING overloads return independent strings. Nonletters and embedded NUL bytes are preserved; use ASCII for predictable case conversion. - `ASC(CHAR)` and `ASC(STRING)` return the unsigned character or first-byte code; an empty string returns zero. - `CHR(Code)` returns a one-byte STRING containing the low eight bits. `LENGTH(CHR(0))` is 1. -- `NUM_TO_STR(INTEGER)` and `NUM_TO_STR(REAL)` use C++17 `std::to_string`, with six fractional digits for REAL. +- `NUM_TO_STR(INTEGER)` and `NUM_TO_STR(REAL)` convert INTEGER to decimal text and REAL to the shortest round-trip text (Python `repr` style, identical to OUTPUT: `2.0`, `0.1`, `1e-07`, `inf`). - `STR_TO_NUM(S)` returns REAL through the same `parseNumber` helper as IS_NUM (`strtod`, full consumption). Invalid text and trailing junk throw `STR_TO_NUM: '<text>' is not a number`; overflow throws `... is out of the REAL range`; underflow is accepted. - `IS_NUM(S)` agrees with STR_TO_NUM: full consumption by `strtod` and no overflow, without throwing. Leading whitespace is accepted; trailing whitespace, trailing junk, empty input, embedded NUL bytes, and overflowing values (`1e999`) are rejected. |
