Result Word
Explanation:
1. The source value specified by S is a degree, and the instruction is used to get the tangent of
the source value specified by S. After the tangent value is gotten, the sign is stored in D, the
integer part is stored in D+1, and the fractional part is stored in D+2.
2. The range of degrees: 0°≦Degree＜360°
3. The operation result is rounded off to the fifth decimal place.
4. If the conversion result is 0, SM600 is ON.
Example:
The instruction is used to get the tangent of the value in D0. After the tangent value is gotten, the
sign is stored in D10, the integer part is stored in D11, and the fractional part is stored in D12.
