The schema is SYSIBM.
Returns the hyperbolic arctangent of the argument, where the argument is an angle expressed in radians.
The argument can be of any built-in numeric data type (except for DECFLOAT). It is converted to a double-precision floating-point number for processing by the function.
The result of the function is a double-precision floating-point number. The result can be null if the argument can be null or the database is configured with dft_sqlmathwarn set to YES; the result is the null value if the argument is null.
