This function is only available when connected to a Teradata database.
The standard inverse Hyperbolic Sine function is supported, generating ASINH (expression) and returning a value of type float. When dragging a Hyperbolic Arcsine operator into a variable, the following tree element is created.
Variable Creation > Input > Variables: SQL Elements pane - Trigonometric > Hyperbolic Arcsine
Columns and/or other expressions can be moved into the (empty) branch of the tree. There are no special properties for the Hyperbolic Arcsine operator.
