/**
 ArcSin routines.
 There are two basic format for the evaluation method in
 this routine:
 1, eval(a) -> c
 a is the parameter of the evaluation function to do
 asin(a) pointwise and the result is passed out as c
 2. eval(dest, a) -> c
 a, b are the parameter of the evaluation function and
 <tt>dest</tt> is the temporary space to hold the result.
 The method returns the reference to <tt>dest</tt>.
