Returns the tangent of the specified angle expressed in degrees.
TAND(x)
x is a floating-point value representing an angle and cannot be an odd multiple of 90.
TAND(45.0) /* returns 1.0 */
A TAND 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 TAND function returns the tangent of the angle x expressed in degrees. The result has the same data type as x.
