Function: Sine
This macro command is used to store a sine 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 sin 90° in radians;
$u200 = RAD (90) (F)
$u100 = SIN ($u200) (F)
The operation result of "1" is stored in $u100.
The sine, cosine and tangent of the
trigonometric functions can be
obtained based on the formula given
to the right.
• Radian (circular measure)
1 rad = 360/2π =
Approx. 57.29578 degrees
Supplementary information
• $s1056 stores the result of macro execution.

* An indefinite value is stored in [F0].
• To convert the unit of an angle, use the macro command of DEG (page 23-11) or RAD (page
23-12).
