sincos (sm4 - asm)

  • Article

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.

src -inf -F -denorm -0 +0 +denorm +F +inf NaN
destSIN NaN [-1 to +1] -0 -0 +0 +0 [-1 to +1] NaN NaN
destCOS NaN [-1 to +1] +1 +1 +1 +1 [-1 to +1] NaN NaN
