// 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.
