Description
The sind(a) function is a degree argument trigonometric function. It
computes the sine of vector elements multiplied by π
/180. For an
argument a
, the function computes sin(π
*a
/180).
Note that arguments abs(a
i) ≤ 224 for single
precision or abs(a
i ) ≤ 252 for double
precision, they belong to the fast computational path:
trigonometric function arguments for which VM provides the best
possible performance. Avoid arguments with do not belong to the fast
computational path in VM High Accuracy (HA) or Low Accuracy (LA)
functions. For arguments which do not belong to the fast
computational path you can use VM Enhanced Performance (EP)
functions, which are fast on the entire function domain. However,
these functions provide lower accuracy.
