The TAN function returns the tangent of the argument, where the argument is an angle expressed in radians. The TAN and ATAN functions are inverse operations.
The data type of the result is double-precision floating point. If the argument can be null, the result can be null; if the argument is null, the result is the null value.
SELECT TAN(:TANGENT) FROM SYSIBM.SYSDUMMY1Returns the approximate value 14.10.
