tuple_numbertuple_numberTupleNumberTupleNumber (Operator)

Name

tuple_numbertuple_numberTupleNumberTupleNumber — Convert a tuple (of strings) into a tuple of numbers.

Signature

tuple_number( : : T : Number)

Herror tuple_number(const char* T, double* Number)

Herror T_tuple_number(const Htuple T, Htuple* Number)

void TupleNumber(const HTuple& T, HTuple* Number)

HTuple HTuple::TupleNumber() const

static void HOperatorSet.TupleNumber(HTuple t, out HTuple number)

HTuple HTuple.TupleNumber()

Description

tuple_numbertuple_numberTupleNumberTupleNumberTupleNumber converts the input tuple TTTTt into a tuple of numbers. If the input tuple contains numbers, they are simply copied into the output tuple. Strings are converted into the appropriate type of number (integer or floating point numbers) or are copied as strings if they do not represent a number. Note that strings starting with 0x are interpreted as hexadecimal numbers, and strings starting with 0 as octal numbers. For example, the string '20' is converted to the integer 20, '020' to 16, and '0x20' to 32.

Exception: Empty input tuple

If the input tuple is empty, the operator returns an empty tuple.
