+// History
+//==============================================================
+// 2/02/00  Initial version 
+// 8/17/00  New and much faster algorithm.
+// 8/31/00  Avoided bank conflicts on loads, shortened |x|=1 path, 
+//          fixed mfb split issue stalls.
+// 12/19/00 Fixed small arg cases to force inexact, or inexact and underflow.
+
+// Description
+//=========================================
+// The asin function computes the principle value of the arc sine of x.
+// asin(0) returns 0, asin(1) returns pi/2, asin(-1) returns -pi/2.
+// A doman error occurs for arguments not in the range [-1,+1].
+
+// The asin function returns the arc sine in the range [-pi/2, +pi/2] radians.
