Purpose
Returns the tangent of the specified angle expressed in radians.
Parameters
x is a floating-point value representing an angle and cannot be an odd multiple of Π/2.
Examples
TAN(0.0) /* returns 0.0 */
Restrictions
A TAN operation on floating-point decimal data is actually performed using the floating-point binary operation. Thus, the range of the operands and the result of the operation are limited to the ranges for floating-point binary numbers.
Description
The TAN function returns the tangent of the angle x expressed in radians. The result has the same data type as x.
