COMPUTE THE NATURAL LOG OF A NUMBER¶
Computes the natural logarithm (base e) of a given scalar number. Use this worker anywhere a ln(x) transformation is needed in a data pipeline or mathematical expression.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Number | numberwhosenaturallogistobecomputed | scalar | — | ✓ | The scalar numeric value x for which ln(x) is computed; must be a positive real number (x > 0). |
| Format | format | text | %s | ✓ | Optional printf-style format string (e.g. ‘%.4f’) used to format the output; defaults to ‘%s’ which returns the full floating-point string representation. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| math_log_output_1 | math_log_output_1 | scalar | Scalar result of ln(x), formatted according to the ‘format’ input; a floating-point number returned as a string. |
