Function: Tangent
This macro command is used to store a tangent of the angle (in radians) specified for [F1] in [F0].
Specify values for [F0] and [F1] in the format of decimal floating-point data (FLOAT).

Example
• To obtain the value for tan 45° in radians;
$u200 = RAD (45) (F)
$u100 = TAN ($u200) (F)
The operation result of "1" is stored in $u100.
* For more information on tanθ of the trigonometric functions, refer to "Example" of sine on
page 23-5.
Supplementary information
• $s1056 stores the result of macro execution.

*1 An indefinite value is stored in [F0].
*2 When the value specified for [F1] is π × (0.5 + n), "-1" is stored in [F0]. (n: integer)
• To convert the unit of an angle, use the macro command of DEG (page 23-11) or RAD (page
23-12).
