tuple_log2tuple_log2TupleLog2TupleLog2tuple_log2 (Operator)
Name
tuple_log2tuple_log2TupleLog2TupleLog2tuple_log2 — Compute the base 2 logarithm of a tuple.
Signature
Herror tuple_log2(double T, double* Log)
Herror T_tuple_log2(const Htuple T, Htuple* Log)
def tuple_log2(t: MaybeSequence[Union[float, int]]) -> Sequence[float]
def tuple_log2_s(t: MaybeSequence[Union[float, int]]) -> float
Description
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:
Log := log2(T)
Execution Information
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters

Input tuple.
Restriction:
T > 0
LogLogLogLogloglog (output_control) number(-array) → HTupleSequence[float]HTupleHtuple (real) (double) (double) (double)
Base 2 logarithm of the input tuple.
