18.18 FNC130 – SIN / Floating Point Sine
Outline
This instruction obtains the sine value of an angle (in radians).
→ For handling of floating point, refer to Subsection 5.1.3.
1. Instruction format
2. Set data
3. Applicable devices
Explanation of function and operation
1. 32-bit operation (DSIN and DSINP)
A value of angle (binary floating point) specified in [
+1, 
] is converted into the sine value, and transferred
to [
+1, 
].
