Name
tuple_logtuple_logTupleLogTupleLog — Compute the natural logarithm of a tuple.
Herror tuple_log(double T, double* Log)
Herror T_tuple_log(const Htuple T, Htuple* Log)
tuple_logtuple_logTupleLogTupleLogTupleLog computes the natural logarithm of the input tuple
TTTTt. The natural logarithm is always returned as a floating
point number. The natural 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_logtuple_logTupleLogTupleLogTupleLog,
which can be used in an expression in the following syntax:
Log := log(T)
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
TTTTt (input_control) number(-array) → HTupleHTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)
