tuple_log10tuple_log10TupleLog10TupleLog10tuple_log10 — Compute the base 10 logarithm of a tuple.

Signature

tuple_log10( : : T : Log)

Herror tuple_log10(double T, double* Log)

Herror T_tuple_log10(const Htuple T, Htuple* Log)

void TupleLog10(const HTuple& T, HTuple* Log)

HTuple HTuple::TupleLog10() const

static void HOperatorSet.TupleLog10(HTuple t, out HTuple log)

HTuple HTuple.TupleLog10()

def tuple_log10(t: MaybeSequence[Union[float, int]]) -> Sequence[float]

def tuple_log10_s(t: MaybeSequence[Union[float, int]]) -> float

Description

tuple_log10tuple_log10TupleLog10TupleLog10tuple_log10 computes the base 10 logarithm of the input tuple TTTtt. 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_log10tuple_log10TupleLog10TupleLog10tuple_log10, which can be used in an expression in the following syntax:

Log := log10(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

TTTtt (input_control)  number(-array) → HTupleMaybeSequence[Union[float, int]]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)

Input tuple.

Restriction: T > 0

LogLogLogloglog (output_control)  number(-array) → HTupleSequence[float]HTupleHtuple (real) (double) (double) (double)

Base 10 logarithm of the input tuple.
