   .. rubric:: Description
      :class: sectiontitle


   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``\ :sub:`i`) ≤ 2\ :sup:`24` for single
   precision or abs(``a``\ :sub:`i` ) ≤ 2\ :sup:`52` 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.
