sincos (sm4 - asm)
Component-wise sin(theta) and cos(theta) for theta in radians.
| sincos[_sat] destSIN[.mask], destCOS[.mask], [-]src0[_abs][.swizzle] |
|---|
| Item | Description |
|---|---|
| destSIN |
[in] The address of sin(src0), computed per component. |
| destCOS |
[in] The address of cos(src0), computed per component. |
| src0 |
[in] The components for which to compute sin and cos. |
Remarks
If the result is not needed, you can specify destSIN and destCOS as NULL instead of specifying a register.
Theta values can be any IEEE 32-bit floating point values.
The maximum absolute error is 0.0008 in the interval from -100*Pi to +100*Pi.
The following table shows the results obtained when executing the instruction with various classes of numbers.
F means finite-real number.
