Herror tuple_log2(double T, double* Log)

Herror T_tuple_log2(const Htuple T, Htuple* Log)

void TupleLog2(const HTuple& T, HTuple* Log)

HTuple HTuple::TupleLog2() const

static void HOperatorSet.TupleLog2(HTuple t, out HTuple log)

HTuple HTuple.TupleLog2()

def tuple_log2(t: MaybeSequence[Union[float, int]]) -> Sequence[float]

def tuple_log2_s(t: MaybeSequence[Union[float, int]]) -> float


tuple_log2tuple_log2TupleLog2TupleLog2TupleLog2tuple_log2 computes the base 2 logarithm of the input tuple TTTTtt. The logarithm is always returned as a floating point number. The logarithm of a string is not allowed.

Exception: Empty input tuple

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

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_log2tuple_log2TupleLog2TupleLog2TupleLog2tuple_log2, which can be used in an expression in the following syntax:
